  • SQLAuthority News – Technology and Online Learning – Personal Technology Tip

    - by pinaldave
    This is the fourth post in my series about Personal Technology Tips and Tricks, and I knew exactly what I wanted to write about.  But at first I was conflicted.   Is online learning really a personal tip?  Is it really a trick that no one knows?  However, I have decided to stick with my original idea because online learning is everywhere.  It’s a trick that we can’t – and shouldn’t – overlook.  Here are ten of my ideas about how we should be taking advantage of online learning. 1) Get ahead in the work place.  We all know that a good way to become better at your job, and to become more competitive for promotions and raises.  Many people overlook online learning as a way to get job training, though, thinking it is a path for people still seeking their high school or college diplomas.  But take a look at what companies like Pluralsight offer, and you might be pleasantly surprised. 2) Flexibility.  Some of us remember the heady days of college with nostalgia, others remember it with loathing.  A lot of bad memories come from remembering the strict scheduling and deadlines of college.  But with online learning, the classes fit into your free time – you don’t have to schedule your life around classes.  Even better, there are usually no homework or test deadlines, only one final deadline where all work must be completed.  This allows students to work at their own pace – my next point. 3) Learn at your own pace.  One thing traditional classes suffer from is that they are highly structured.  If you work more quickly than the rest of the class, or especially if you work more slowly, traditional classes do not work for you.  Online courses let you move as quickly or as slowly as you find necessary. 4) Fill gaps in your knowledge.  I’m sure I am not the only one who has thought to myself “I would love to take a course on X, Y, or Z.”  The problem is that it can be very hard to find the perfect class that teaches exactly what you’re interested in, at a time and a price that’s right.  But online courses are far easier to tailor exactly to your tastes. 5) Fits into your schedule.  Even harder to find than a class you’re interested in is one that fits into your schedule.  If you hold down a job – even a part time job – you know it’s next to impossible to find class times that work for you.  Online classes can be taken anytime, anywhere.  On your lunch break, in your car, or in your pajamas at the end of the day. 6) Student centered.  Online learning has to stay competitive.  There are hundreds, even thousands of options for students, and every provider has to find a way to lure in students and provide them with a good education.  The best kind of online classes know that they need to provide great classes, flexible scheduling, and high quality to attract students – and the student benefit from this kind of attention. 7) You can save money.  The average cost for a college diploma in the US is over $20,000.  I don’t know about you, but that is not the kind of money I just have lying around for a rainy day.  Sometimes I think I’d love to go back to school, but not for that price tag.  Online courses are much, much more affordable.  And even better, you can pick and choose what courses you’d like to take, and avoid all the “electives” in college. 8) Get access to the best minds in the business.  One of the perks of being the best in your field is that you are one person who knows the most about something.  If students are lucky, you will choose to share that knowledge with them on a college campus.  For the hundreds of other students who don’t live in your area and don’t attend your school, they are out of luck.  But luckily for them, more and more online courses is attracting the best minds in the business, and if you enroll online, you can take advantage of these minds, too. 9) Save your time.  Getting a four year degree is a great decision, and I encourage everyone to pursue their Bachelor’s – and beyond.  But if you have already tried to go to school, or already have a degree but are thinking of switching fields, four years of your life is a long time to go back and redo things.  Getting your online degree will save you time by allowing you to work at your own pace, set your own schedule, and take only the classes you’re interested in. 10) Variety of degrees and programs.  If you’re not sure what you’re interested in, or if you only need a few classes here and there to finish a program, online classes are perfect for you.  You can pick and choose what you’d like, and sample a wide variety without spending too much money. I hope I’ve outlined for everyone just a few ways that they could benefit from online learning.  If you’re still unconvinced, just check out a few of my other articles that expand more on these topics.

  • SQLAuthority News – Storing Data and Files in Cloud – Dropbox – Personal Technology Tip

    - by pinaldave
    I thought long and hard about doing a Personal Technology Tips series for this blog.  I have so many tips I’d like to share.  I am on my computer almost all day, every day, so I have a treasure trove of interesting tidbits I like to share if given the chance.  The only thing holding me back – which tip to share first?  The first tip obviously has the weight of seeming like the most important.  But this would mean choosing amongst my favorite tricks and shortcuts.  This is a hard task. Source: Dropbox.com My Dropbox I have finally decided, though, and have determined that the first Personal Technology Tip may not be the most secret or even trickier to master – in fact, it is probably the easiest.  My today’s Personal Technology Tip is Dropbox. I hope that all of you are nodding along in recognition right now.  If you do not use Dropbox, or have not even heard of it before, get on the internet and find their site.  You won’t be disappointed.  A quick recap for those in the dark: Dropbox is an online storage site with a lot of additional syncing and cloud-computing capabilities.  Now that we’ve covered the basics, let’s explore some of my favorite options in Dropbox. Collaborate with All The first thing I love about Dropbox is the ability it gives you to collaborate with others.  You can share files easily with other Dropbox users, and they can alter them, share them with you, all while keeping track of different versions in on easy place.  I’d like to see anyone try to accomplish that key idea – “easily” – using e-mail versions and multiple computers.  It’s even difficult to accomplish using a shared network. Afraid that this kind of ease looks too good to be true?  Afraid that maybe there isn’t enough storage space, or the user interface is confusing?  Think again.  There is plenty of space – you can get 2 GB with just a free account, and upgrades are inexpensive and go up to 100 GB of storage.  And the user interface is so easy that anyone can learn to use it. What I use Dropbox for I love Dropbox because I give a lot of presentations and often they are far from home.  I can keep my presentations on Dropbox and have easy access to them anywhere, without needing to have my whole computer with me.  This is just one small way that you can use Dropbox. You can sync your entire hard drive, or hard drives if you have multiple computers (home, work, office, shared), and you can set Dropbox to automatically sync files on a certain timeline, or whenever Dropbox notices that they’ve been changed. Why I love Dropbox Dropbox has plenty of storage, but 2 GB still has a hard time competing with the average desktop’s storage space.  So what if you want to sync most of your files, but only the ones you use the most and share between work and home, and not all your files (especially large files like pictures and videos)?  You can use selective sync to choose which files to sync. Above all, my favorite feature is LanSync.  Dropbox will search your Local Area Network (LAN) for new files and sync them to Dropbox, as well as downloading the new version to all the shared files across the network.  That means that if move around on different computers at work or at home, you will have the same version of the file every time.  Or, other users on the LAN will have access to the new version, which makes collaboration extremely easy. Ref: rzfeeser.com Dropbox has so many other features that I feel like I could create a Personal Technology Tips series devoted entirely to Dropbox.  I’m going to create a bullet list here to make things shorter, but I strongly encourage you to look further into these into options if it sounds like something you would use. Theft Recover Home Security File Hosting and Sharing Portable Dropbox Sync your iCal calendar Password Storage What is your favorite tool and why? I could go on and on, but I will end here.  In summary – I strongly encourage everyone to investigate Dropbox to see if it’s something they would find useful.  If you use Dropbox and know of a great feature I failed to mention, please share it with me, I’d love to hear how everyone uses this program.

  • SQLAuthority News – Windows Efficiency Tricks and Tips – Personal Technology Tip

    - by pinaldave
    This is the second post in my series about my favorite Technology Tips, and I wanted to focus on my favorite Microsoft product.  Choosing just one topic to cover was too hard, though.  There are so many interesting things I have to share that I am forced to turn this second installment into a five-part post.  My five favorite Windows tips and tricks. 1) You can open multiple applications using the task bar. With the new Windows 7 taskbar, you can start navigating with just one click.  For example, you can launch Word by clicking on the icon on your taskbar, and if you are using multiple different programs at the same time, you can simply click on the icon to return to Word.  However, what if you need to open another Word document, or begin a new one?  Clicking on the Word icon is just going to bring you back to your original program.  Just click on the Word icon again while holding down the shift key, and you’ll open up a new document. 2) Navigate the screen with the touch of a button – and not your mouse button. Yes, we live in a pampered age.  We have access to amazing technology, and it just gets better every year.  But have you ever found yourself wishing that right when you were in the middle of something, you didn’t have to interrupt your work flow be reaching for your mouse to navigate through the screen?  Yes, we have all been guilty of this pampered wish.  But Windows has delivered!  Now you can move your application window using your arrow keys. Lock the window to the left, right hand screen: Win+left Arrow and Win+right Arrow Maximize & minimize: Win+up arrow and Win+down arrow Minimize all items on screen: Win+M Return to your original folder, or browse through all open windows: Alt+up arrow, Alt+Left Arrow, or Alt+right arrow Close down or reopen all windows: win+home 3) Are you one of the few people who still uses Command Prompt? You know who you are, and you aren’t ashamed to still use this option that so many people have forgotten about it.  You can easily access it by holding down the shift key while RIGHT clicking on any folder. 4) Quickly select multiple files without using your mouse. We all know how to select multiple files or folders by Ctrl-clicking or Shift-clicking multiple items.  But all of us have tried this, and then accidentally released Ctrl, only to lose all our precious work.  Now there is a way to select only the files you want through a check box system.  First, go to Windows Explorer, click Organize, and then “Folder and Search Options.”  Go to the View tab, and under advanced settings, you can find a box that says “Use check boxes to select items.”  Once this has been selected, you will be able to hover your mouse over any file and a check box will appear.  This makes selecting multiple, random files quick and easy. 5) Make more out of remote access. If you work anywhere in the tech field, you are probably the go-to for computer help with friends and family, and you know the usefulness of remote access (ok, some of us use this extensively at work, as well, but we all have friends and family who rely on our skills!).  Often it is necessary to restart a computer, which is impossible in remote access as the computer will not show the shutdown menu.  To force the computer to do your wishes, we return to Command Prompt.  Open Command Prompt and type “shutdown /s” for shutdown, or “shutdown /r” for restart. I hope you will find above five tricks which I use in my daily use very important.

  • Personal Technology – Excel Tip: Comparing Excel Files

    - by Pinal Dave
    This guest post is by Vinod Kumar. Vinod Kumar has worked with SQL Server extensively since joining the industry over a decade ago. Working on various versionsfrom SQL Server 7.0, Oracle 7.3 and other database technologies – he now works with the Microsoft Technology Center (MTC) as a Technology Architect. Let us read the blog post in Vinod’s own voice. I have been writing about Excel Tips over my blog and thought it would be great to share one interesting tips here as a guest blog here. Assume a situation where you want to compare multiple excel files. Here is a typical scenario I have encountered as a common activity. Assume you are sending an Excel file with tons of data, formulae and multiple sheets. Now you are requesting your colleague to validate the file and if required change content for correctness. After receiving the file from your colleague, now you want to know what changes were made by this person to your document. Now here is a cool new addition to Excel 2013 that can help you achieve this task. To get to this option, click the INQUIRE Tab. Incase you don’t have the INQUIRE Tab, check Options using INQUIRE blog. In that post, we discuss all the other options of INQUIRE tab. Once you are on the INQUIRE Tab, select “Compare Files” button as shown in the figure above. This brings a dialog as below. If you are on Windows 8 or Windows 7 OS, search for an application called “Spreadsheet Compare 2013”. Ultimately both the options lead us to the same application. If you are using the stand alone app, once the App initializes, click the “Compare files” options from the toolbar. Make sure to give two different Excel files as shown in the figure above. After selecting the Excel Sheets, you can see the Compare tool has a number of other options to play from. We will talk about some of them later in this post. Just below our toolbar is a colorful side-by-side comparison of both our excel sheets. We can also see the various Tab’s from each file. There is a meaning for each of our color coding which will be discussed next. As you saw above, the color coding has a meaning. For example the bottom pane lists each of the color coding and most importantly each of the changes as compared side-by-side. The detailed information shown below can be exported using the “Export Results” options from the toolbar as a separate Excel Workbook or can be copied to clipboard to be used later. The final piece of the puzzle is to show a graphical view of these differences results based on each category. We cannot drill down per se, but this is a great way to know that the maximum changes seem to be based on “Cell Formats” and then few “Calculated Values” have changed. The INQUIRE option and Spreadsheet Compare 2013 tool is part of Excel 2013. So as you explore using the new version of Excel, there are many such hidden features that are worth exploring. Do let us know if you enjoyed learning a new feature today and I hope you will play around with this feature in your day-today challenges when working with Excel files.

  • SQLAuthority News – Android Efficiency Tips and Tricks – Personal Technology Tip #003

    - by pinaldave
    I use my phone for lots of things.  I use it mainly to replace my tablet – I can e-mail, take and edit photos, and do almost everything I can do on a laptop with this phone.  And I am sure that there are many of you out there just like me.  I personally have a Galaxy S3, which uses the Android operating system, and I have decided to feature it as the third installment of my Technology Tips and Tricks series. 1) Shortcut to your favorite contacts on home screen Access your most-called contacts easily from your home screen by holding your finger on any empty spot on the home screen.  A menu will pop up that allows you to choose Shortcuts, and Contact.  You can scroll through your contact list and then just tap on the name of the person you want to be able to dial with a single click. 2) Keep track of your data usage Yes, we all should keep a close eye on our data usage, because it is very easy to go over our limits and then end up with a giant bill at the end of the month.  Never get surprised when you open that mobile phone envelope again.  Go to Settings, then Data Usage, and you can find a quick rundown of your usage, how much data each app uses, and you can even set alarms to let you know when you are nearing the limits.   Better yet, you can set the phone to stop using data when it reaches a certain limit. 3) Bring back Good Grammar We often hear proclamations about the downfall of written language, and how texting abbreviations, misspellings, and lack of punctuation are the root of all evil.  Well, we can show all those doomsdayers that all is not lost by bringing punctuation back to texting.  Usually we leave it off when we text because it takes too long to get to the screen with all the punctuation options.  But now you can hold down the period (or “full stop”) button and a list of all the commonly-used punctuation marks will pop right up. 4) Apps, Apps, Apps and Apps And finally, I cannot end an article about smart phones without including a list of my favorite apps.  Here are a list of my Top 10 Applications on my Android (not counting social media apps). Advanced Task Killer – Keeps my phone snappy by closing un-necessary apps WhatsApp - my favorite alternate to Text SMS Flipboard - my ‘timepass’ moments Skype – keeps me close to friends and family GoogleMaps - I am never lost because of this one thing Amazon Kindle – Books my best friends DropBox - My data always safe Pluralsight Player – Learning never stops for me Samsung Kies Air – Connecting Phone to Computer Chrome – Replacing default browser I have not included any social media applications in the above list, but you can be sure that I am linked to Twitter, Facebook, Google+, LinkedIn, and YouTube.

  • SQL SERVER – What is a Technology Evangelist?

    - by pinaldave
    When you hear that someone is an “evangelist” the first thing that might pop into your mind is the Christian church.  In fact, the term did come from Christianity, and basically means someone who spreads the news about their faith.  In the technology world, the same definition is true. Technology evangelists are individuals who, professionally or in their spare time, spread the news about the latest new products.  Sounds like a salesperson, right?  No they are absolutely different. Salespeople also keep up to date with a large number of people, and like to convince others to buy their product – and some will go to any lengths to sell!  An evangelist, on the other hand, is brutally honest about the product, even if sometimes it means not making a sale.  An evangelist is out there to tell the TRUTH.  A salesperson needs to make sales. An Evangelist offers a Solution independent of Technology used – a Salesperson offers Particular Technology. With this definition in mind, you can probably think of a few technology evangelists you already know.  Maybe it’s a relative or a neighbor, someone who loves keeping up with the latest trends and is always willing to tell you about them if you ask even the simplest question.  And, in fact, they probably are evangelists and don’t even know it.  For a long time, the work of technology evangelism was in the hands of community and community technology leaders. Luckily now various organizations have understood the importance of the community and helping community to reach their goals. This has lead them to create role of “Technology Evangelists”. Let me talk about one of the most famous Evangelist of the SQL Server technology. Technology Evangelist only belongs to technology and above any country, race, location or any other thing. They are dedicated to the technology. Vinod Kumar is such a man, who have given a lot to community. For years he was a Technology Evangelist for Microsoft, and maintained a blog that was dedicated to spreading his enthusiasm for his favorite products.  He is one of the most respected Evangelists in the field, and has done a lot of work to define the job for other professionals. Vinod’s career has since progressed to the Microsoft Technology Center (read his post), but he is continuing to be a strong presence in the evangelism community.  I have a lot of respect for Vinod.  He has done a lot for the community and technology evangelism.  Everybody has dream to serve community the way he does, and he is a great role model for evangelists everywhere. On his blog, Vinod created one of the best descriptions of a Technology Evangelist.  It defined the position and also made the distinction between evangelist and salesperson extremely clear.  I will include the highlights of that list here, because no one can say it better than Vinod: Bundle of energy – Passion is their middle name Wonderful Story tellers Empathy, Trust, Loyalty, Openness, Accessibility and Warmth Technology Enthusiast – Doers Love people, people and more people – Community oriented Unique Style and Leadership qualities !!! Self-Confident, Self-Motivated but a student (To read the full list, see: Evangelism Beyond Borders with Evangelists) His blog is a must-read for anyone interested in technology evangelism as a career or simply a hobby.  His advice about how to gain an audience and become a trusted advisor is the best in the business. I think there is an evangelist in everyone. I, too, consider myself a technology evangelist.  Regular readers of this blog will recognize that I am dedicated to bringing information to the masses, and that I pride myself on being both brutally and honest and giving every product fair consideration. I think there is no better way of saying following subject. “Once an Evangelist – Always an Evangelist!” Reference: Pinal Dave (http://blog.SQLAuthority.com)     Filed under: About Me, Database, MVP, Pinal Dave, PostADay, SQL, SQL Authority, SQL Query, SQL Server, SQL Tips and Tricks, SQLAuthority News, T SQL, Technology Tagged: Evangelist

  • Deciding which technology to use is a big decision when no technology is an obvious choice

    Deciding which technology to use in a new venture or project is a big decision for any company when no technology is an obvious choice. It is always best to analyze the current requirements of the project, and also evaluate the existing technology climate so that the correct technology based on the situation at the time is selected. When evaluation the requirements of a new project it is best to be open to as many technologies as possible initially so a company can be sure that the right decision gets made. Another important aspect of the technology decision is what can the current network and  hardware environment handle, and what would be needed to be adjusted if a specific technology was selected. For example if the current network operating system is Linux then VB6 would force  a huge change in the current computing environment. However if the current network operation system was windows based then very little change would be needed to allow for VB6 if any change had to be done at all. Finally and most importantly an analysis should be done regarding the current technical employees pertaining to their skills and aspirations. For example if you have a team of Java programmers then forcing them to build something in C# might not be an ideal situation. However having a team of VB.net developers who want to develop something in C# would be a better situation based on this example because they are already failure with the .Net Framework and have a desire to use the new technology. In addition to this analysis the cost associated with building and maintaining the project is also a key factor. If two languages are ideal for a project but one technology will increase the budget or timeline by 50% then it might not be the best choice in that situation. An ideal situation for developing in C# applications would be a project that is built on existing Microsoft technologies. An example of this would be a company who uses Windows 2008 Server as their network operating system, Windows XP Pro as their main operation system, Microsoft SQL Server 2008 as their primary database, and has a team of developers experience in the .net framework. In the above situation Java would be a poor technology decision based on their current computing environment and potential lack of Java development by the company’s developers. It would take the developers longer to develop the application due the fact that they would have to first learn the language and then become comfortable with the language. Although these barriers do exist, it does not mean that it is not due able if the company and developers were committed to the project.

  • High load average due to high system cpu load (%sys)

    - by Nick
    We have server with high traffic website. Recently we moved from 2 x 4 core server (8 cores in /proc/cpuinfo), 32 GB RAM, running CentOS 5.x, to 2 x 4 core server (16 cores in /proc/cpuinfo), 32 GB RAM, running CentOS 6.3 Server running nginx as a proxy, mysql server and sphinx-search. Traffic is high, but mysql and sphinx-search databases are relatively small, and usually everything works blazing fast. Today server experienced load average of 100++. Looking at top and sar, we noticed that (%sys) is very high - 50 to 70%. Disk utilization was less 1%. We tried to reboot, but problem existed after the reboot. At any moment server had at least 3-4 GB free RAM. Only message shown by dmesg was "possible SYN flooding on port 80. Sending cookies.". Here is snippet of sar 11:00:01 CPU %user %nice %system %iowait %steal %idle 11:10:01 all 21.60 0.00 66.38 0.03 0.00 11.99 We know that this is traffic issue, but we do not know how to proceed future and where to check for solution. Is there a way we can find where exactly those "66.38%" are used. Any suggestions would be appreciated.

  • SQLAuthority News – SQL Server Technology Evangelists and Evangelism

    - by pinaldave
    This is the exact conversation that I had with three people during the recent SQL Server Public Training. Person 1: “Are you an SQL Server Evangelist?” Pinal : “No, but Vinod Kumar is.” Person 1: “Who are you?” Person 2: “He is Pinal, haha!” Person 1: “I know that, but don’t you evangelize SQL Server Technology?” Pinal : “Hmm… I do that…” Person 1: “In that case, why don’t you call yourself an Evangelist?” Pinal : “…! …” Person 2: “Good Question! Who are you Pinal?” Pinal : “I think you are asking my title, is that correct?” Person 1: “Maybe.” Pinal : “I am a Mentor, and I work for Solid Quality Mentors.” Person 2: “I have seen you listing yourself as the Founder of SQLAuthority.com… so…” Pinal : “Yeah that’s true.” Person 3: “Let me summarize what these people are asking. What they are asking is that you can have multiple titles, so is being an evangelist one of your titles or not?” Pinal : “Well, I am an SQL Server MVP and lots of people say that we are also evangelists of technology. In fact,  we are all evangelists of technology, aren’t we?” Person 1: “So let me come back to my original topic: If you are an SQL Server Evangelist, then what is this evangelism?” Person 2: “And who is Vinod Kumar – I have heard about him a lot.” Pinal : “Oh okay. Now I got it. Let me explain …” The answer was quite long but since this conversation, I have been thinking about the words “evangelist” and “evangelism.” I think being an evangelist is one of the most respected jobs in the world and to do this job one must bear lots of responsibilities. There were two questions asked to me, so let me answer both one by one. Who is Vinod Kumar? Vinod Kumar is a Technology Evangelist for Microsoft and one of the most respected persons in the SQL Server Community in India. Let me copy-paste my note from the previous TechEd India 2010 article. “I attended 2 sessions of Vinod Kumar. Vinod is a natural storyteller so there was no doubt that his sessions would be jam-packed. People attended his sessions simply because Vinod was the best speaker in the event.

  • high load average, high wait, dmesg raid error messages (debian nfs server)

    - by John Stumbles
    Debian 6 on HP proliant (2 CPU) with raid (2*1.5T RAID1 + 2*2T RAID1 joined RAID0 to make 3.5T) running mainly nfs & imapd (plus samba for windows share & local www for previewing web pages); with local ubuntu desktop client mounting $HOME, laptops accessing imap & odd files (e.g. videos) via nfs/smb; boxes connected 100baseT or wifi via home router/switch uname -a Linux prole 2.6.32-5-686 #1 SMP Wed Jan 11 12:29:30 UTC 2012 i686 GNU/Linux Setup has been working for months but prone to intermittently going very slow (user experience on desktop mounting $HOME from server, or laptop playing videos) and now consistently so bad I've had to delve into it to try to find what's wrong(!) Server seems OK at low load e.g. (laptop) client (with $HOME on local disk) connecting to server's imapd and nfs mounting RAID to access 1 file: top shows load ~ 0.1 or less, 0 wait but when (desktop) client mounts $HOME and starts user KDE session (all accessing server) then top shows e.g. top - 13:41:17 up 3:43, 3 users, load average: 9.29, 9.55, 8.27 Tasks: 158 total, 1 running, 157 sleeping, 0 stopped, 0 zombie Cpu(s): 0.4%us, 0.4%sy, 0.0%ni, 49.0%id, 49.7%wa, 0.0%hi, 0.5%si, 0.0%st Mem: 903856k total, 851784k used, 52072k free, 171152k buffers Swap: 0k total, 0k used, 0k free, 476896k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 3935 root 20 0 2456 1088 784 R 2 0.1 0:00.02 top 1 root 20 0 2028 680 584 S 0 0.1 0:01.14 init 2 root 20 0 0 0 0 S 0 0.0 0:00.00 kthreadd 3 root RT 0 0 0 0 S 0 0.0 0:00.00 migration/0 4 root 20 0 0 0 0 S 0 0.0 0:00.12 ksoftirqd/0 5 root RT 0 0 0 0 S 0 0.0 0:00.00 watchdog/0 6 root RT 0 0 0 0 S 0 0.0 0:00.00 migration/1 7 root 20 0 0 0 0 S 0 0.0 0:00.16 ksoftirqd/1 8 root RT 0 0 0 0 S 0 0.0 0:00.00 watchdog/1 9 root 20 0 0 0 0 S 0 0.0 0:00.42 events/0 10 root 20 0 0 0 0 S 0 0.0 0:02.26 events/1 11 root 20 0 0 0 0 S 0 0.0 0:00.00 cpuset 12 root 20 0 0 0 0 S 0 0.0 0:00.00 khelper 13 root 20 0 0 0 0 S 0 0.0 0:00.00 netns 14 root 20 0 0 0 0 S 0 0.0 0:00.00 async/mgr 15 root 20 0 0 0 0 S 0 0.0 0:00.00 pm 16 root 20 0 0 0 0 S 0 0.0 0:00.02 sync_supers 17 root 20 0 0 0 0 S 0 0.0 0:00.02 bdi-default 18 root 20 0 0 0 0 S 0 0.0 0:00.00 kintegrityd/0 19 root 20 0 0 0 0 S 0 0.0 0:00.00 kintegrityd/1 20 root 20 0 0 0 0 S 0 0.0 0:00.02 kblockd/0 21 root 20 0 0 0 0 S 0 0.0 0:00.08 kblockd/1 22 root 20 0 0 0 0 S 0 0.0 0:00.00 kacpid 23 root 20 0 0 0 0 S 0 0.0 0:00.00 kacpi_notify 24 root 20 0 0 0 0 S 0 0.0 0:00.00 kacpi_hotplug 25 root 20 0 0 0 0 S 0 0.0 0:00.00 kseriod 28 root 20 0 0 0 0 S 0 0.0 0:04.19 kondemand/0 29 root 20 0 0 0 0 S 0 0.0 0:02.93 kondemand/1 30 root 20 0 0 0 0 S 0 0.0 0:00.00 khungtaskd 31 root 20 0 0 0 0 S 0 0.0 0:00.18 kswapd0 32 root 25 5 0 0 0 S 0 0.0 0:00.00 ksmd 33 root 20 0 0 0 0 S 0 0.0 0:00.00 aio/0 34 root 20 0 0 0 0 S 0 0.0 0:00.00 aio/1 35 root 20 0 0 0 0 S 0 0.0 0:00.00 crypto/0 36 root 20 0 0 0 0 S 0 0.0 0:00.00 crypto/1 203 root 20 0 0 0 0 S 0 0.0 0:00.00 ksuspend_usbd 204 root 20 0 0 0 0 S 0 0.0 0:00.00 khubd 205 root 20 0 0 0 0 S 0 0.0 0:00.00 ata/0 206 root 20 0 0 0 0 S 0 0.0 0:00.00 ata/1 207 root 20 0 0 0 0 S 0 0.0 0:00.14 ata_aux 208 root 20 0 0 0 0 S 0 0.0 0:00.01 scsi_eh_0 dmesg suggests there's a disk problem: ..............

(I'm guessing I could buy a larger drive if the price is right: I'm thinking that one day I'll need to grow the size of the array and that would be one less drive to replace with a larger one) then use mdadm to fail out the existing sdc, remove it and fit the new drive fdisk the new drive with the same size partition for the array as the old one had use mdadm to add the new drive into the array that sound OK?

  • Is your team is a high-performing team?

    As a child I can remember looking out of the car window as my father drove along the Interstate in Florida while seeing prisoners wearing bright orange jump suits and prison guards keeping a watchful eye on them. The prisoners were taking part in a prison road gang. These road gangs were formed to help the state maintain the state highway infrastructure. The prisoner’s primary responsibilities are to pick up trash and debris from the roadway. This is a prime example of a work group or working group used by most prison systems in the United States. Work groups or working groups can be defined as a collection of individuals or entities working together to achieve a specific goal or accomplish a specific set of tasks. Typically these groups are only established for a short period of time and are dissolved once the desired outcome has been achieved. More often than not group members usually feel as though they are expendable to the group and some even dread that they are even in the group. "A team is a small number of people with complementary skills who are committed to a common purpose, performance goals, and approach for which they are mutually accountable." (Katzenbach and Smith, 1993) So how do you determine that a team is a high-performing team?  This can be determined by three base line criteria that include: consistently high quality output, the promotion of personal growth and well being of all team members, and most importantly the ability to learn and grow as a unit. Initially, a team can successfully create high-performing output without meeting all three criteria, however this will erode over time because team members will feel detached from the group or that they are not growing then the quality of the output will decline. High performing teams are similar to work groups because they both utilize a collection of individuals or entities to accomplish tasks. What distinguish a high-performing team from a work group are its characteristics. High-performing teams contain five core characteristics. These characteristics are what separate a group from a team. The five characteristics of a high-performing team include: Purpose, Performance Measures, People with Tasks and Relationship Skills, Process, and Preparation and Practice. A high-performing team is much more than a work group, and typically has a life cycle that can vary from team to team. The standard team lifecycle consists of five states and is comparable to a human life cycle. The five states of a high-performing team lifecycle include: Formulating, Storming, Normalizing, Performing, and Adjourning. The Formulating State of a team is first realized when the team members are first defined and roles are assigned to all members. This initial stage is very important because it can set the tone for the team and can ultimately determine its success or failure. In addition, this stage requires the team to have a strong leader because team members are normally unclear about specific roles, specific obstacles and goals that my lay ahead of them.  Finally, this stage is where most team members initially meet one another prior to working as a team unless the team members already know each other. The Storming State normally arrives directly after the formulation of a new team because there are still a lot of unknowns amongst the newly formed assembly. As a general rule most of the parties involved in the team are still getting used to the workload, pace of work, deadlines and the validity of various tasks that need to be performed by the group.  In this state everything is questioned because there are so many unknowns. Items commonly questioned include the credentials of others on the team, the actual validity of a project, and the leadership abilities of the team leader.  This can be exemplified by looking at the interactions between animals when they first meet.  If we look at a scenario where two people are walking directly toward each other with their dogs. The dogs will automatically enter the Storming State because they do not know the other dog. Typically in this situation, they attempt to define which is more dominating via play or fighting depending on how the dogs interact with each other. Once dominance has been defined and accepted by both dogs then they will either want to play or leave depending on how the dogs interacted and other environmental variables. Once the Storming State has been realized then the Normalizing State takes over. This state is entered by a team once all the questions of the Storming State have been answered and the team has been tested by a few tasks or projects.  Typically, participants in the team are filled with energy, and comradery, and a strong alliance with team goals and objectives.  A high school football team is a perfect example of the Normalizing State when they start their season.  The player positions have been assigned, the depth chart has been filled and everyone is focused on winning each game. All of the players encourage and expect each other to perform at the best of their abilities and are united by competition from other teams. The Performing State is achieved by a team when its history, working habits, and culture solidify the team as one working unit. In this state team members can anticipate specific behaviors, attitudes, reactions, and challenges are seen as opportunities and not problems. Additionally, each team member knows their role in the team’s success, and the roles of others. This is the most productive state of a group and is where all the time invested working together really pays off. If you look at an Olympic figure skating team skate you can easily see how the time spent working together benefits their performance. They skate as one unit even though it is comprised of two skaters. Each skater has their routine completely memorized as well as their partners. This allows them to anticipate each other’s moves on the ice makes their skating look effortless. The final state of a team is the Adjourning State. This state is where accomplishments by the team and each individual team member are recognized. Additionally, this state also allows for reflection of the interactions between team members, work accomplished and challenges that were faced. Finally, the team celebrates the challenges they have faced and overcome as a unit. Currently in the workplace teams are divided into two different types: Co-located and Distributed Teams. Co-located teams defined as the traditional group of people working together in an office, according to Andy Singleton of Assembla. This traditional type of a team has dominated business in the past due to inadequate technology, which forced workers to primarily interact with one another via face to face meetings.  Team meetings are primarily lead by the person with the highest status in the company. Having personally, participated in meetings of this type, usually a select few of the team members dominate the flow of communication which reduces the input of others in group discussions. Since discussions are dominated by a select few individuals the discussions and group discussion are skewed in favor of the individuals who communicate the most in meetings. In addition, Team members might not give their full opinions on a topic of discussion in part not to offend or create controversy amongst the team and can alter decision made in meetings towards those of the opinions of the dominating team members. Distributed teams are by definition spread across an area or subdivided into separate sections. That is exactly what distributed teams when compared to a more traditional team. It is common place for distributed teams to have team members across town, in the next state, across the country and even with the advances in technology over the last 20 year across the world. These teams allow for more diversity compared to the other type of teams because they allow for more flexibility regarding location. A team could consist of a 30 year old male Italian project manager from New York, a 50 year old female Hispanic from California and a collection of programmers from India because technology allows them to communicate as if they were standing next to one another.  In addition, distributed team members consult with more team members prior to making decisions compared to traditional teams, and take longer to come to decisions due to the changes in time zones and cultural events. However, team members feel more empowered to speak out when they do not agree with the team and to notify others of potential issues regarding the work that the team is doing. Virtual teams which are a subset of the distributed team type is changing organizational strategies due to the fact that a team can now in essence be working 24 hrs a day because of utilizing employees in various time zones and locations.  A primary example of this is with customer services departments, a company can have multiple call centers spread across multiple time zones allowing them to appear to be open 24 hours a day while all a employees work from 9AM to 5 PM every day. Virtual teams also allow human resources departments to go after the best talent for the company regardless of where the potential employee works because they will be a part of a virtual team all that is need is the proper technology to be setup to allow everyone to communicate. In addition to allowing employees to work from home, the company can save space and resources by not having to provide a desk for every team member. In fact, those team members that randomly come into the office can actually share one desk amongst multiple people. This is definitely a cost cutting plus given the current state of the economy. One thing that can turn a team into a high-performing team is leadership. High-performing team leaders need to focus on investing in ongoing personal development, provide team members with direction, structure, and resources needed to accomplish their work, make the right interventions at the right time, and help the team manage boundaries between the team and various external parties involved in the teams work. A team leader needs to invest in ongoing personal development in order to effectively manage their team. People have said that attitude is everything; this is very true about leaders and leadership. A team takes on the attitudes and behaviors of its leaders. This can potentially harm the team and the team’s output. Leaders must concentrate on self-awareness, and understanding their team’s group dynamics to fully understand how to lead them. In addition, always learning new leadership techniques from other effective leaders is also very beneficial. Providing team members with direction, structure, and resources that they need to accomplish their work collectively sounds easy, but it is not.  Leaders need to be able to effectively communicate with their team on how their work helps the company reach for its organizational vision. Conversely, the leader needs to allow his team to work autonomously within specific guidelines to turn the company’s vision into a reality.  This being said the team must be appropriately staffed according to the size of the team’s tasks and their complexity. These tasks should be clear, and be meaningful to the company’s objectives and allow for feedback to be exchanged with the leader and the team member and the leader and upper management. Now if the team is properly staffed, and has a clear and full understanding of what is to be done; the company also must supply the workers with the proper tools to achieve the tasks that they are asked to do. No one should be asked to dig a hole without being given a shovel.  Finally, leaders must reward their team members for accomplishments that they achieve. Awards could range from just a simple congratulatory email, a party to close the completion of a large project, or other monetary rewards. Managing boundaries is very important for team leaders because it can alter attitudes of team members and can add undue stress to the team which will force them to loose focus on the tasks at hand for the group. Team leaders should promote communication between team members so that burdens are shared amongst the team and solutions can be derived from hearing the opinions of multiple sources. This also reinforces team camaraderie and working as a unit. Team leaders must manage the type and timing of interventions as to not create an even bigger mess within the team. Poorly timed interventions can really deflate team members and make them question themselves. This could really increase further and undue interventions by the team leader. Typically, the best time for interventions is when the team is just starting to form so that all unproductive behaviors are removed from the team and that it can retain focus on its agenda. If an intervention is effectively executed the team will feel energized about the work that they are doing, promote communication and interaction amongst the group and improve moral overall. High-performing teams are very import to organizations because they consistently produce high quality output and develop a collective purpose for their work. This drive to succeed allows team members to utilize specific talents allowing for growth in these areas.  In addition, these team members usually take on a sense of ownership with their projects and feel that the other team members are irreplaceable.

  • Suggestions for programming language and database for a high end database querying system (>50 milli

    - by mmdave
    These requirements are sketchy at the moment, but will appreciate any insights. We are exploring what would be required to build a system that can handle 50 database million queries a day - specifiically from the programming language and database choice Its not a typical website, but an API / database accessing through the internet. Speed is critical. The application will primarily receive these inputs (about a few kb each) and will have to address each of them via the database lookup. Only a few kb will be returned. The server will be run over https/ssl.

  • Weekly technology meeting?

    - by Mag20
    I am thinking of introducing weekly technology meeting where programmers working on the same project can discuss things like: current status of the project on technical side technology backlog. Things that we may have skipped because of deadlines but now coming back to bite us. technology constraints that are limiting developers from being productive new and emerging technologies that may apply to the project Basically looking at the project from programmer's perspective, not the business side. - What would be some good guidelines for a meeting like this? How long should the meeting last? Is weekly too often? Should we time-limit each topic? What kinda of topics are good for a meeting like this and which ones are bad? Is 10 people too many? ...

  • SQLAuthority News – 2 Whitepapers Announced – AlwaysOn Architecture Guide: Building a High Availability and Disaster Recovery Solution

    - by pinaldave
    Understanding AlwaysOn Architecture is extremely important when building a solution with failover clusters and availability groups. Microsoft has just released two very important white papers related to this subject. Both the white papers are written by top experts in industry and have been reviewed by excellent panel of experts. Every time I talk with various organizations who are adopting the SQL Server 2012 they are always excited with the concept of the new feature AlwaysOn. One of the requests I often here is the related to detailed documentations which can help enterprises to build a robust high availability and disaster recovery solution. I believe following two white paper now satisfies the request. AlwaysOn Architecture Guide: Building a High Availability and Disaster Recovery Solution by Using AlwaysOn Availability Groups SQL Server 2012 AlwaysOn Availability Groups provides a unified high availability and disaster recovery (HADR) solution. This paper details the key topology requirements of this specific design pattern on important concepts like quorum configuration considerations, steps required to build the environment, and a workflow that shows how to handle a disaster recovery. AlwaysOn Architecture Guide: Building a High Availability and Disaster Recovery Solution by Using Failover Cluster Instances and Availability Groups SQL Server 2012 AlwaysOn Failover Cluster Instances (FCI) and AlwaysOn Availability Groups provide a comprehensive high availability and disaster recovery solution. This paper details the key topology requirements of this specific design pattern on important concepts like asymmetric storage considerations, quorum model selection, quorum votes, steps required to build the environment, and a workflow. If you are not going to implement AlwaysOn feature, this two Whitepapers are still a great reference material to review as it will give you complete idea regarding what it takes to implement AlwaysOn architecture and what kind of efforts needed. One should at least bookmark above two white papers for future reference.

  • High load (and high temp) with idle processes

    - by Nanne
    I've got a semi-old laptop (toshiba satellite a110-228), that's appointed 'laptop for the kids' by my sister. I've installed ubuntu netbook (10.10) on it because of the lack-of memory and it seems to work fine, accept from some heat-issues. These where never a problem under windows. It looks like I've got something similar to this problem: Load is generally 1 or higher, sometimes its stuck at 0.80, but its way to high. Top/htop only show a couple of percentage CPU use (which isn't too shocking, as i'm not doing anything). At this point all the software is stock, and i'd like to keep it that way because its supposed to be the easy-to-maintain kids computer. Now I'd like to find out: What could be the cause of the high load? Could it be as this thread implies, some driver, are there other options to check? How could I see what is really keeping the system hot and bothered? How to check what runs, etc etc? I'd like to pinpoint the culprint. further steps to take for debugging? The big bad internet leads me to believe that it might be the graphics drivers. The laptop has an Intel 945M chipset, but that doesn't seem to be one of the problem childs in this manner (I read a lot abotu ATI drivers that need special isntall). I'd not only welcome hints to directly solve this (duh) but also help in starting to debug what is going on. I am really hesitant in installing an older kernel, as I want it to be stock, and easy upgradeable (because I don't live near it, it should run without me ;) ) As an afterthought: to keep the whole thing cooler, can I 'amp up' the fancontrol? Its only going "airplane" mode when the computer is 95 Celcius, which is a tad late for my taste. Top: powertop:

  • Technology/Programming mailing lists How do you manage?

    - by AdityaGameProgrammer
    Email Alerts, Blog /Forum updates, discussion subscriptions general programming/technology update emails that we often subscribe to.Do you actually read them ? or go direct to the source when you find time. Often we might the mail of programmers filled with loads of unread subscription mail from technology they previously were following or worked on or things they wish to follow .Some or a majority of these mail just keep on piling up . I personally have few updates that i wish i read but constantly avoid and keep of for latter and finally delete them in effort keep the in box clean. Few questions come to mind regarding this Do you keep such mail in separate accounts? Do you read all the mail you have subscribed to? Do you ever unsubscribe to any such email if you aren't reading them? How much do you really value these email. Lastly do you keep your in box clean ? wish to deal with this in a better way.

  • How to be a responsible early adopter?

    - by Gaurav
    A disconcertingly high number of new technologies/paradigms are overhyped (as is evident from replies to this question). Combine this with the fact that being early adopter is inherently risky. This makes evaluation of technology before adoption critical. So how exactly early adopters among you go about it. I can think of following general criteria. For early adoption technology must address previously unaddressed issue and/or For acceptance beyond early adoption technology should address performance One indicator that something is not right is when there is too much of jargon for technology which is either irrelevant or there is no evidence to back it up What is your opinion. Update: 4. BTW, the biggest reason to fear technology is when it is imposed by the tech-unaware management based entirely on number of buzzwords.

  • Soda Cans Exploding Under the Stress of High Voltage [Video]

    - by Jason Fitzpatrick
    In an effort to start your Monday off in true Mad Scientist style, we bring you soda cans being decimated by thousands of volts in a “Thumper”. What is a thumper, you ask? During office hours, it’s a high-voltage testing unit most often used to stress test electric cables. In the off hours, however, the electrical engineering geeks over at The Geek Group like to shove anywhere from a few hundred to thousands of volts through unsuspecting objects to see what happens. In this installation they’re shooting high voltage through a variety of soft drink cans with an end result that sounds and looks like a cannon loaded with Mountain Dew.

  • What is the status in 3D technology for TVs [closed]

    - by Eduardo Molteni
    Maybe it is off-topic for programmers.SE, but don't know where else to ask, and I trust my fellow programmers :) I've recently being lightly following new 3D technologies and I thought that glass-free 3D TV was about to take over the scene since it make much more sense to TVs (I can't imagine having glasses for all the family, kids breaking them, etc) But it seems that I'm wrong, since LG, Sony and Samsumg keep fighting over glasses (active-passive) What is the current and future status in 3D technology for TVs?
