  • Why are marketing employees, product managers, etc. deserving of their own office, yet programmers are jammed in a room as many as possible?

    - by TheImirOfGroofunkistan
    I don't understand why many (many) companies treat software developers like they are assembly line workers making widgets. Joel Spolsky has a great example of the problems this creates: With programmers, it's especially hard. Productivity depends on being able to juggle a lot of little details in short term memory all at once. Any kind of interruption can cause these details to come crashing down. When you resume work, you can't remember any of the details (like local variable names you were using, or where you were up to in implementing that search algorithm) and you have to keep looking these things up, which slows you down a lot until you get back up to speed. Here's the simple algebra. Let's say (as the evidence seems to suggest) that if we interrupt a programmer, even for a minute, we're really blowing away 15 minutes of productivity. For this example, lets put two programmers, Jeff and Mutt, in open cubicles next to each other in a standard Dilbert veal-fattening farm. Mutt can't remember the name of the Unicode version of the strcpy function. He could look it up, which takes 30 seconds, or he could ask Jeff, which takes 15 seconds. Since he's sitting right next to Jeff, he asks Jeff. Jeff gets distracted and loses 15 minutes of productivity (to save Mutt 15 seconds). Now let's move them into separate offices with walls and doors. Now when Mutt can't remember the name of that function, he could look it up, which still takes 30 seconds, or he could ask Jeff, which now takes 45 seconds and involves standing up (not an easy task given the average physical fitness of programmers!). So he looks it up. So now Mutt loses 30 seconds of productivity, but we save 15 minutes for Jeff. Ahhh! Quote Link More Spolsky on Offices Why don't managers and owner's see this?

  • How can I transfer files to a Kindle Fire with a Micro-USB cable?

    - by Jeff
    I'm running Ubuntu 11.10, and when I connect my Kindle Fire to my computer via micro usb, it is not recognized automatically. Other usb devices, such as my ipod and digital camera, are recognized just fine. It does not appear to be a usb power issue, since the Kindle Fire wakes up from sleeping when it is plugged in. I never get the message on the Kindle telling me it is ready to accept files from the computer, though. Here are the last 15 lines of dmesg after plugging the kindle in: jeff@prime:~$ dmesg | tail -n 15 [45918.269671] ieee80211 phy0: wl_ops_bss_info_changed: arp filtering: enabled true, count 1 (implement) [45929.072149] wlan0: no IPv6 routers present [46743.224217] usb 1-1: new high speed USB device number 5 using ehci_hcd [46743.364623] scsi8 : usb-storage 1-1:1.0 [46744.366102] scsi 8:0:0:0: Direct-Access Amazon Kindle 0001 PQ: 0 ANSI: 2 [46744.366356] scsi: killing requests for dead queue [46744.372494] scsi: killing requests for dead queue [46744.384510] scsi: killing requests for dead queue [46744.392348] scsi: killing requests for dead queue [46744.392731] scsi: killing requests for dead queue [46744.396853] scsi: killing requests for dead queue [46744.397214] scsi: killing requests for dead queue [46744.400795] scsi: killing requests for dead queue [46744.401589] sd 8:0:0:0: Attached scsi generic sg2 type 0 [46744.407520] sd 8:0:0:0: [sdb] Attached SCSI removable disk And here are my mounted filesystems: jeff@prime:~$ df Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda1 298594984 174663712 108763480 62% / udev 1407684 4 1407680 1% /dev tmpfs 566924 896 566028 1% /run none 5120 0 5120 0% /run/lock none 1417308 300 1417008 1% /run/shm /home/jeff/.Private 298594984 174663712 108763480 62% /home/jeff I should note that, since I got Dropbox working on my Kindle, the usb is no longer strictly necessary, but as a matter of principle I'd love to get it working.

  • SQL SERVER – Service Broker and CAP_CPU_PERCENT – Limiting SQL Server Instances to CPU Usage

    - by pinaldave
    I have mentioned several times on this blog that the best part of blogging is the questions I receive from readers. They are often very interesting. The questions from readers give me a good idea what other readers might be thinking as well. After reading my earlier article Simple Example to Configure Resource Governor – Introduction to Resource Governor – I received an email from a reader and we exchanged a few emails. After exchanging emails we both figured out what is going on. It was indeed interesting and reader suggested to that I should blog about it.  I asked for permission to publish his name but he does not like the attention so we will just call him Jeff. I have converted our emails into chat for easy consumption. Jeff: Your script does not work at all. I think either there is a bug in SQL Server. Pinal: Would you please explain in detail? Jeff: Your code does not limit the CPU usage? Pinal: How did you measure it? Jeff: Well, we have third party tools for it but let us say I have limited the resources for Reporting Services and used your script described in your blog. After that I ran only reporting service workload the CPU is still used more than 100% and it is not limited to 30% as described in your script. Clearly something is wrong somewhere. Pinal: Did you say you ONLY ran reporting server load? Jeff: Yeah, to validate I ran ONLY reporting server load and CPU did not throttle at 30% as per your script. Pinal: Oh! I get it here is the answer - CAP_CPU_PERCENT = 30. Use it. Jeff: What is that, I think your earlier script says it will throttle the Reporting Service workload and Application/OLTP workload and balance it. Pinal: Exactly, that is correct. Jeff: You need to write more in email buddy! Just like your blogs, your answers do not make sense! No Offense! Pinal: Hmm…feedback well taken. Let me try again. In SQL Server 2012 there are a few enhancements with regards to SQL Server Resource Governor. One of the enhancement is how the resources are allocated. Let me explain you with examples. Configuration: [Read Earlier Post] Reporting Workload: MIN_CPU_PERCENT=0, MAX_CPU_PERCENT=30 Application/OLTP Workload: MIN_CPU_PERCENT=50, MAX_CPU_PERCENT=100 Example 1: If there is only Reporting Workload on the server: SQL Server will not limit usage of CPU to only 30% workload but SQL Server instance will use all available CPU (if needed). In another word in this scenario it will use more than 30% CPU. Example 2: If there is Reproting Workload and heavy Application/OLTP workload: SQL Server will allocate a maximum of 30% CPU resources to Reporting Workload and allocate remaining resources to heavy application/OLTP workload. The reason for this enhancement is for better utilization of the resources. Let us think, if there is only single workload, which we have limited to max CPU usage to 30%. The other unused available CPU resources is now wasted. In this situation SQL Server allows the workload to use more than 30% resources leading to overall improved/optimized performance. However, in the case of multiple workload where lots of resources are needed the limits specified in MAX_CPU_PERCENT are acknowledged. Example 3: If there is a situation where the max CPU workload has to be enforced: This is a very interesting scenario, in the case when the max CPU workload has to be enforced irrespective of the workload and enhanced algorithm, the keyword CAP_CPU_PERCENT is essential. It specifies a hard cap on the CPU bandwidth that all requests in the resource pool will receive. It will never let CPU usage for reporting workload to go over 30% in our case. You can use the key word as follows: -- Creating Resource Pool for Report Server CREATE RESOURCE POOL ReportServerPool WITH ( MIN_CPU_PERCENT=0, MAX_CPU_PERCENT=30, CAP_CPU_PERCENT=40, MIN_MEMORY_PERCENT=0, MAX_MEMORY_PERCENT=30) GO Notice that there is MAX_CPU_PERCENT=30 and CAP_CPU_PERCENT=40, what it means is that when SQL Server Instance is under heavy load under different workload it will use the maximum CPU at 30%. However, when the SQL Server instance is not under workload it will go over the 30% limit. However, as CAP_CPU_PERCENT is set to 40, it will not go over 40% in any case by limiting the usage of CPU. CAP_CPU_PERCENT puts a hard limit on the resources usage by workload. Jeff: Nice Pinal, you should blog about it. [A day passes by] Pinal: Jeff, it is done! Click here to read it.

  • Podcast Show Notes: Evolving Enterprise Architecture

    - by Bob Rhubart
    The latest series of ArchBeat podcast programs grew out of another virtual meet-up, held on March 11. As with previous meet-ups, I sent out a general invitation to the roster of previous ArchBeat panelists to join me on Skype to talk about whatever topic comes up. For this event, Oracle ACE Directors Mike van Alst and Jordan Braunstein  showed up, along with Oracle product manager Jeff Davies.  The result was an impressive and wide-ranging discussion on the evolution of Enterprise Architecture, the role of technology in EA, the impact of social computing, and challenge of having three generations of IT people at work in the enterprise – each with different perspectives on technology. Mike, Jordan, and Jeff talked for more than an hour, and the conversation was so good that slicing and dicing it to meet the time constraints for these podcasts has been a challenge. The first two segments of the conversation are now available. Listen to Part 1 Listen to Part 2 Part 3 will go live next week, and an unprecedented fourth segment will follow. These guys have strong opinions, and while there is common ground, they don’t always agree. But isn’t that what a community is all about? I suspect that you’ll have questions and comments after listening, so I encourage you to reach out to Mike, Jordan, and Jeff  via the following links: Mike van Alst Blog | Twitter | LinkedIn | Business |Oracle Mix | Oracle ACE Profile Jordan Braunstein Blog | Twitter | LinkedIn | Business | Oracle Mix | Oracle ACE Profile Jeff Davies Homepage | Blog | LinkedIn | Oracle Mix (Also check out Jeff’s book: The Definitive Guide to SOA: Oracle Service Bus)   Coming Soon ArchBeat’s microphones were there for the panel discussions at the recent Oracle Technology Network Architect Days in Dallas and Anaheim.

  • Setup mod-rewrite

    - by Publiccert
    I'm trying to setup mod-rewrite for a few servers. The code lives in /home/jeff/www/upload/application/ However, this is what's happening. It appears to be a problem with mod-rewrite since it's appending code.py to the beginning of the directory: The requested URL /code.py/home/jeff/www/upload/application/ was not found on this server. Here are the rules. Which one is the culprit?

  • ffmpeg 0.5 flv to wav conversion creates wav files that other programs won't open.

    - by superrebel
    Hi, I am using the following command to convert FLV files to audio files to feed into julian, a speech to text program. cat ./jon2.flv | ffmpeg -i - -vn -acodec pcm_s16le -ar 16000 -ac 1 -f wav - | cat - > jon2.wav The cat's are there for debugging purposes as the final use will be a running program that will pipe FLV into ffmpeg's stdin and the stdout going to julian. The resulting wave files are identified by "file" as: jon3.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono 16000 Hz VLC (based on ffmpeg) plays the file, but no other tools will open/see the data. They show empty wav files or won't open/play. For example Sound Booth from CS4. Has anyone else had similar problems? Julian requires wav files 16bit mono at 16000 Hz. Julian does seem to read the file, but doesn't seem to go through the entire file (may be unrelated). Thanks, -rr

    - by Jeff Julian
    I have been recently been doing more photography and Flickr was only allowing me to do so much with the images in displaying them.  No customization of skin, no page grouping, no post like pages.  So I decided to host a WordPress blog to host my images.  I really wanted to try WordPress to see what features single-hosted blog products offer that our multiple-hosted blog system could take advantage of.  So far the product is very cool, I can see how such a large developer network would help produce such cool “apps” for WP.  The product makes if very easy to make changes to your hosted environment that would be a little scary for a multiple blog host.  I need to compare features for their hosted solution. Any who, FotoJeff.com is my new photography blog home.  I have been working with the Kansas City Rescue Mission a lot lately so most of my shots are for them. FotoJeff.com – Photography Blog of Jeff Julian My hope is to make this blog again my technology blog, Staff of Geeks our Geekswithblogs.net announcement blog and FotoJeff.com my photography blog.  I need to start dog fooding my thoughts on blogging and keep the noise down (by making more noise with this post :D).

  • AJI Report #19 | Scott K Davis and his son Tommy on Gamification and Programming for Kids

    - by Jeff Julian
    We are very excited about this show. John and Jeff sat down with Scott Davis and his son Tommy to talk about Gamification and Programming for Kids. Tommy is nine years old and the Iowa Code Camp was his second time presenting. Scott and Tommy introduce a package called Scratch that was developed by MIT to teach kids about logic and interacting with programming using sprites. Tommy's favorite experience with programming right now is Lego Mindstorms because of the interaction with the Legos and the development. Most adults when they get started with development also got started with interacting more with the physical machines. The next generation is given amazing tools, but the tools tend to be sealed and the physical interaction is not there. With some of these alternative hobby platforms like Legos, Arduino, and .NET Micro Framework, kids can write some amazing application and see their code work with physical movement and interaction with devices and sensors. In the second half of this podcast, Scott talks about how companies can us Gamification to prompt employees to interact with software and processes in the organization. We see gamification throughout the consumer space and you need to do is open up the majority of the apps on our phones or tablets and there is some interaction point to give the user a reward for using the tool. Scott gets into his product Qonqr which is described as the board game Risk and Foursquare together. Scott gets into the different mindsets of gamers (Bartle Index) and how you can use these mindsets to get the most out of your team through gamification techniques.

    For the second year in a row, my friend and colleague Jeff Blankenburg has created what is quickly proving to live up to it’s namesake – the Toughest Developer Puzzle Ever. Some of the puzzles are technical, some are not but all require that you understand the web, development and technology to solve. Even if you don’t get in on the fantastic prizes that Jeff has lined up, there’s great bragging rights in being able to solve the Toughest Developer Puzzle Ever. This year, I was honored enough to get to create three of the puzzles myself – let me know what you think of them. I’m not going to tell you which ones I created now and definitely don’t ask me for hints – Jeff has threatened me if I give any of the puzzle away… ;) All I can say now is “Good luck!”

  • Query only the first detail record for each master record

    - by Neal S.
    If I have the following master-detail relationship: owner_tbl auto_tbl --------- -------- owner --- owner auto year And I have the following table data: owner_tbl auto_tbl --------- -------- john john, corvette, 1968 john, prius, 2008 james james, f-150, 2004 james, cadillac, 2002 james, accord, 2009 jeff jeff, tesla, 2010 jeff, hyundai, 1996 Now, I want to perform a query that returns the following result: john, corvette, 1968 jeff, hyundai, 1996 james, cadillac, 2002 The query should join the two tables, and sort all the records on the "year" field, but only return the first detail record for each master record. I know how to join the tables and sort on the "year" field, but it's not clear how (or if) I might be able to only retrieve the first joined record for each owner. Three related questions: Can I perform this kind of query using LINQ-to-SQL? Can I perform the query using T-SQL? Would it be best to just create a stored procedure for the query given its likely complexity?

  • Warm Reception By Partners at EMEA Manageability Forum

    - by Get_Specialized!
    For the EMEA Partners that were able to attend the event in Istanbul Turkey, thank you for your attendance and feedback at the event. As you can see, the weather kept most of inside during the event and at times there was even some snow.  And while it may have been chilly outside, there was a warm reception from Partners who traveled from all over EMEA to hear from other Oracle Specialized Partners and subject matter experts about the opportunities and benefits of Oracle Enterprise Manager and Exadata Specialization. Here you can see David Robo, Oracle Technology Director for Manageability kicking off the event followed later by Patrick Rood, Oracle Indirect Manageability Business. A special thank you to all the Partner speakers including Ron Tolido, VP and CTO of Application Services Continental Europe Capgemini, who delivered a very innovative keynote where many in attendance learned that Black Swans do exist. And while at break, interactivity among partners continued and it was great to see such innovative partners who had listed their achieved specializations on their business cards. Here we can see Oracle Enterprise Manager customer, Turkish Oracle User Group board member and Blogger Gokhan Atil sharing his product experiences with others attending. Additionally, Christian Trieb of Paragon Data, also shared with other Partners what the German Oracle User Group (DOAG) was doing around manageability and invitation to submit papers for their next event. Here we can see at one of the breaks, one of the event organizers Javier Puerta (left), Oracle Director of Partner Programs, joined by Sebastiaan Vingerhoed (middle), Oracle EE & CIS Manager Manageability and speaker on Managing the Application Lifecycle, Julian Dontcheff (right), Global Head of Database Management at Accenture. Below is Julian Dontcheff's delivering his partner presentation on Exadata and Lifecycle Management. Just after his plane landed and 1 hour Turkish taxi experience to the event location, Julian still took the time to sit down with me and provide some extra insights on his experiences of managing the enterprise infrastructure with Oracle Enterprise Manager. Below is one of the Oracle Enterprise Management Product Management Team,  Mark McGill, Oracle Principal Product Manager, presenting to Partners on how you can perform Chargeback and Metering with Oracle Enterprise Manager 12c Cloud Control. Overall, it was a great event and an extra thank you to those OPN Specialized Partners who presented, to the Partners that attended, and to those Oracle team members who organized the event and presented.

  • asp.net mvc create a c# class in an ascx file for design purposes

    - by Julian
    Hi, I am developing a web application using asp.net mvc. I have come across the need to Temporarily create a class in the ascx/aspx file. This class will replace the Model during the development of the page. It will also hold some test data for the user to have the chance to see some results. Once we are happy with the layout on the screen, I will inherit the correct Model class through the Control tag. Can you please advise if this is possible and how to do it? This does not work: <% class Modelo { public Guid Guid { get; set; } public string Name { get; set; } } %> Thanks in advance, Be happy - Julian

  • Google Chrome - NETWORK_IP_ADDRESSES_CHANGED - pages only partially load

    - by Julian
    Hi Google Chrome version (8.0.552.224 (Official Build 68599)) I have developed a web site using asp.net mvc and jquery. it uses a lot of ajax. I noticed that occasionally a web page does not complete loading all files from the server. Browsing through forums It seems that this also happens to other people. Looking in to the Chromium Net-Internals ( type: chrome://net-internals/ as a url in the chrome browser ) I noticed that the pages do not complete loading if a NETWORK_IP_ADDRESSES_CHANGED event occurred. Any files that were not fetched from the server before the time of the NETWORK_IP_ADDRESSES_CHANGED event failed to arrive with error (-3) Do you know why the NETWORK_IP_ADDRESSES_CHANGED event occurs? Is there a way to stop it from happening? Thanks and be happy, Julian
