  • Can't add any PPA's after reinstalling Ubuntu 13.10

    - by Michael Clare
    I can't add any PPA's at all after reinstalling Ubuntu 13.10. Here is what it says: michael@MikesKomputer:~$ sudo add-apt-repository ppa:atareao/atareao Cannot add PPA: 'ppa:atareao/atareao'. Please check that the PPA name or format is correct. This repository is working as far as I know. The problem is that I can't add any new repositories. Even if I can use the Software Center, I can't have my system with the add-apt-repository command broken.

  • An XEvent a Day (2 of 31) – Querying the Extended Events Metadata

    - by Jonathan Kehayias
    In yesterdays post, An Overview of Extended Events , I provided some of the necessary background for Extended Events that you need to understand to begin working with Extended Events in SQL Server. After receiving some feedback by email (thanks Aaron I appreciate it), I have changed the post naming convention associated with the post to reflect “2 of 31” instead of 2/31, which apparently caused some confusion in Paul Randal’s and Glenn Berry’s series which were mentioned in the round up post for...(read more)

  • Multi-Threaded Application vs. Single Threaded Application

    Why would we use a multi threaded application vs. a single threaded application? First we must define multithreading. Multithreading is a feature of an operating system that allows programs to run subcomponents or threads in parallel. Typically most applications only need to use one thread because they do not perform time consuming tasks. The use of multiple threads allows an application to distribute long running tasks so that they can be executed in parallel. This gives the user the perceived appearance that the application is working faster due to the fact that while one thread is waiting on an IO process the remaining tasks can make use of the available CPU. The allows working threads to execute in tandem so that they can be competed sooner. Multithreading Benefits Improved responsiveness — Users usually report improved responsiveness compared to single thread applications. Faster applications — Multiple threads can lead to improved application performance. Prioritization — Threads can be assigned a priority which would allow higher priority tasks to take precedence over lower priority tasks. Single Threading Benefits Programming and debugging —These activities are easier compared to multithreaded applications due to the reduced complexity Less Overhead — Threads add overhead to an application When developing multi-threaded applications, the following must be considered. Deadlocks occur when two threads hold a monitor that the other one requires. In essence each task is blocking the other and both tasks are waiting for the other monitor to be released. This forces an application to hang or deadlock. Resource allocation is used to prevent deadlocks because the system determines if approving the resource request will render the system in an unsafe state. An unsafe state could result in a deadlock. The system only approves requests that will lead to safe states. Thread Synchronization is used when multiple threads use the same instance of an object. The threads accessing the object can then be locked and then synchronized so that each task can interact with the static object on at a time.

  • Secure an Application/Software by expiration with Date?

    - by JNL
    I have been working on some software application and I update them every 6 months. Currently, the way I track the date is by extracting the date from the system when the user installes the application, encrypt it and store it in a file locally. Whenever the application is started, it checks if 6 months have passed, then it works or it doesn't, in which case it shows an error message telling the user to update. I wonder whether there is a better way to do this. Any comments or suggestions would be highly appreciated

  • Truly understand the threshold for document set in document library in SharePoint

    - by ybbest
    Recently, I am working on an issue with threshold. The problem is that when the user navigates to a view of the document library, it displays the error message “list view threshold is exceeded”. However, in the view, it has no data. The list view threshold limit is 5000 by default for the non-admin user. This limit is not the number of items returned by your query; it is the total number of items the database needs to read to calculate the returned result set. So although the view does not return any result but to calculate the result (no data to show), it needs to access more than 5000 items in the database. To fix the issue, you need to create an index for the column that you use in the filter for the view. Let’s look at the problem in details. You can download a solution to replicate this issue here. 1. Go to Central Admin ==> Web Application Management ==>General Settings==> Click on Resource Throttling 2. Change the list view threshold in web application from 5000 to 2000 so that I can show the problem without loading more than 5000 items into the list. FROM TO 3. Go to the page that displays the approved view of the Loan application document set. It displays the message as shown below although I do not have any data returned for this view. 4. To get around this, you need to create an index column. Go to list settings and click on the Index columns. 5. Click on the “Create a new index” link. 6. Select the LoanStatus field as I use this filed as the filter to create the view. 7. After the index is created now I can access the approved view, as you can see it does not return any data. Notes: List View Threshold: Specify the maximum number of items that a database operation can involve at one time. Operations that exceed this limit are prohibited.

  • Service Broker Solutions - Don't Forget the Basics

    - by AllenMWhite
    After finally getting a Service Broker solution implemented successfully, I'm really impressed with the technology, and frustrated how difficult it can be to implement and get it really working as expected. First, understand the technology. There are some great resources out there to help you get started. The first place to go is Klaus Aschenbrenner's book, the one that Greg Low reviewed this past week. It's an amazing resource and played a large part in my success. (I bought it for my Kindle, and...(read more)

  • Chroot into a 32 bit version of ubuntu from a 64 bit host

    - by Leif Andersen
    I have a piece of software that only runs on 32 bit linux (Xilinx webPack 10.1, apperently it 'has' to be the old version because that's the latest one compatible with their boards), anyway, this version is only compatible with 32 bit linux. So, I head off to this page to see what I can do: https://help.ubuntu.com/community/32bit_and_64bit Of the 4 options (listed at the bottom): I already installed ia32-libs, and it's still not working I could do that one if needed (which I ended up doing). No, I don't want to be working from a vm all of next semester, that would be painful and I'd rather just reinstall my whole computer to a 32 bit os (which I don't want to do). It didn't sound like it was the best option based on what I've seen. So I went off to do #2, and set up a chroot for 32 bit ubuntu. It linked to this tutorial: https://help.ubuntu.com/community/DebootstrapChroot As I'm running ubuntu 10.10 I made the lucid and newer version changes. Which is to say I wrote: [hardy-i386] description=Ubuntu 8.04 Hardy for i386 directory=/srv/chroot/hardy-i386 personality=linux32 root-users=leif type=directory users=leif to /etc/schroot/chroot.d/hardy-i386 (Note though that I did save it once before I had the file properly formatted, I saved the correct version moments later though). I then ran: $ sudo mkdir -p /srv/chroot/hardy_i386 $ sudo debootstrap --variant=buildd --arch i386 hardy /srv/chroot/hardy_i386 http://archive.ubuntu.com/ubuntu/ Then I ran: $ schroot -l And it showed the proper chroot, but then when I ran: $ schroot -c hardy-i386 -u root I got the following error: E: 10mount: error: Directory '/srv/chroot/hardy-i386' does not exist E: 10mount: warning: Mount location /var/lib/schroot/mount/hardy-i386-80359697-2164-4b10-a05a-89b0f497c4f1 no longer exists; skipping unmount E: hardy-i386-80359697-2164-4b10-a05a-89b0f497c4f1: Chroot setup failed: stage=setup-start Can anyone help me figure out what the problem is? Oh, by the way: /srv/chroot/hardy-i386 most certainly exists. I've also tried it replacing all references with hardy to lucid, to no avail. Oh, one more thing, I did set up the chrome os environment a month back or so: http://www.chromium.org/chromium-os/developer-guide and it had me use something with chmod. So, can anyone figure out what the problem is? Thank you.

  • Don’t just P2V that server for Testing!

    - by Jonathan Kehayias
    If you use virtualization in your company, at some point in time you might be tempted to perform a Physical-To-Virtual conversion, also known as P2V.  The ability to create a complete working copy of a physical server as a virtual machine is really useful for migrating to a virtualized datacenter, but it can also wreak havoc in your environment if you use it to generate a copy of a server for testing and the only change you make is the name of the server.  The Problem: Consider that you...(read more)

  • A toolset for self improvement and learning [closed]

    - by Sebastian
    Possible Duplicate: I’m having trouble learning I've been working as an IT consultant for 1½ years and I am very passionate about programming. Before that I studied MSc Software Engineering and had both a part time job as a developer for a big telecom company. During that time I also took extra courses and earned a SCJP certificate. I have been continuously reading a lot of books during the last 3½ years. Now to my problem. I want to continue learning and become a really, really good developer. Apart from my daytime job as a full time java developer I have taken university courses in, for me, new languages and paradigms. Most recently, android game development and then functional programming with Scala. I've read books, went to conferences and had a couple of presentations for internal training purposes in our local office. I want to have some advice from other people who have previously been in my situation or currently are. What are you guys doing to keep improving yourselves? Here is some things that I have found are working for me: Reading books I've mostly read books about best practices for programming, OO-design, refactoring, design patterns, tdd. Software craftmanship if you like. I keep a reading list and my current book is Apprenticeship patterns. Taking courses In my country we have a really good system for taking online distance courses. I have also taken one course at coursera.org and a highly recommend that platform. Ive looked at courses at oreilly.com, industriallogic, javaspecialists.eu and they seem to be okay. If someone gives these type of courses a really good review, I can probably convince my boss. Workshops that span over a couple of days would probably be harder, but Ive seen that uncle Bob will have one about refactoring and tdd in 6months not far from here.. :) Are their possibly some online learning platforms that I dont know about? Educational videos I've bought uncle bobs videos from cleancoders.com and I highly recommend them. The only thing I dont like is that they are quite expensive and that he talks about astronomy for ~10 minutes in every episode. Getting certified I had a lot of fun and learned a lot when I studied for the SCJP. I have also done some preparation for the microsoft equivalent but never went for it. I think it is a good when selling yourself as a newly graduated student and also will boost your knowledge if your are interested in it. Now I would like others to start sharing their experiences and possibly give me some advice! BR Sebastian

  • Developer’s Life – Attitude and Communication – They Can Cause Problems – Notes from the Field #027

    - by Pinal Dave
    [Note from Pinal]: This is a 27th episode of Notes from the Field series. The biggest challenge for anyone is to understand human nature. We human have so many things on our mind at any moment of time. There are cases when what we say is not what we mean and there are cases where what we mean we do not say. We do say and things as per our mood and our agenda in mind. Sometimes there are incidents when our attitude creates confusion in the communication and we end up creating a situation which is absolutely not warranted. In this episode of the Notes from the Field series database expert Mike Walsh explains a very crucial issue we face in our career, which is not technical but more to relate to human nature. Read on this may be the best blog post you might read in recent times. In this week’s note from the field, I’m taking a slight departure from technical knowledge and concepts explained. We’ll be back to it next week, I’m sure. Pinal wanted us to explain some of the issues we bump into and how we see some of our customers arrive at problem situations and how we have helped get them back on the right track. Often it is a technical problem we are officially solving – but in a lot of cases as a consultant, we are really helping fix some communication difficulties. This is a technical blog post and not an “advice column” in a newspaper – but the longer I am a consultant, the more years I add to my experience in technology the more I learn that the vast majority of the problems we encounter have “soft skills” included in the chain of causes for the issue we are helping overcome. This is not going to be exhaustive but I hope that sharing four pieces of advice inspired by real issues starts a process of searching for places where we can be the cause of these challenges and look at fixing them in ourselves. Or perhaps we can begin looking at resolving them in teams that we manage. I’ll share three statements that I’ve either heard, read or said and talk about some of the communication or attitude challenges highlighted by the statement. 1 – “But that’s the SAN Administrator’s responsibility…” I heard that early on in my consulting career when talking with a customer who had serious corruption and no good recent backups – potentially no good backups at all. The statement doesn’t have to be this one exactly, but the attitude here is an attitude of “my job stops here, and I don’t care about the intent or principle of why I’m here.” It’s also a situation of having the attitude that as long as there is someone else to blame, I’m fine…  You see in this case, the DBA had a suspicion that the backups were not being handled right.  They were the DBA and they knew that they had responsibility to ensure SQL backups were good to go – it’s a basic requirement of a production DBA. In my “As A DBA Where Do I start?!” presentation, I argue that is job #1 of a DBA. But in this case, the thought was that there was someone else to blame. Rather than create extra work and take on responsibility it was decided to just let it be another team’s responsibility. This failed the company, the company’s customers and no one won. As technologists – we should strive to go the extra mile. If there is a lack of clarity around roles and responsibilities and we know it – we should push to get it resolved. Especially as the DBAs who should act as the advocates of the data contained in the databases we are responsible for. 2 – “We’ve always done it this way, it’s never caused a problem before!” Complacency. I have to say that many failures I’ve been paid good money to help recover from would have not happened had it been for an attitude of complacency. If any thoughts like this have entered your mind about your situation you may be suffering from it. If, while reading this, you get this sinking feeling in your stomach about that one thing you know should be fixed but haven’t done it.. Why don’t you stop and go fix it then come back.. “We should have better backups, but we’re on a SAN so we should be fine really.” “Technically speaking that could happen, but what are the chances?” “We’ll just clean that up as a fast follow” ..and so on. In the age of tightening IT budgets, increased expectations of up time, availability and performance there is no room for complacency. Our customers and business units expect – no demand – the best. Complacency says “we will give you second best or hopefully good enough and we accept the risk and know this may hurt us later. Sometimes an organization will opt for “good enough” and I agree with the concept that at times the perfect can be the enemy of the good. But when we make those decisions in a vacuum and are not reporting them up and discussing them as an organization that is different. That is us unilaterally choosing to do something less than the best and purposefully playing a game of chance. 3 – “This device must accept interference from other devices but not create any” I’ve paraphrased this one – but it’s something the Federal Communications Commission – a federal agency in the United States that regulates electronic communication – requires of all manufacturers of any device that could cause or receive interference electronically. I blogged in depth about this here (http://www.straightpathsql.com/archives/2011/07/relationship-advice-from-the-fcc/) so I won’t go into much detail other than to say this… If we all operated more on the premise that we should do our best to not be the cause of conflict, and to be less easily offended and less upset when we perceive offense life would be easier in many areas! This doesn’t always cause the issues we are called in to help out. Not directly. But where we see it is in unhealthy relationships between the various technology teams at a client. We’ll see teams hoarding knowledge, not sharing well with others and almost working against other teams instead of working with them. If you trace these problems back far enough it often stems from someone or some group of people violating this principle from the FCC. To Sum It Up Technology problems are easy to solve. At Linchpin People we help many customers get past the toughest technological challenge – and at the end of the day it is really just a repeatable process of pattern based troubleshooting, logical thinking and starting at the beginning and carefully stepping through to the end. It’s easy at the end of the day. The tough part of what we do as consultants is the people skills. Being able to help get teams working together, being able to help teams take responsibility, to improve team to team communication? That is the difficult part, and we get to use the soft skills on every engagement. Work on professional development (http://professionaldevelopment.sqlpass.org/) and see continuing improvement here, not just with technology. I can teach just about anyone how to be an excellent DBA and performance tuner, but some of these soft skills are much more difficult to teach. If you want to get started with performance analytics and triage of virtualized SQL Servers with the help of experts, read more over at Fix Your SQL Server.

  • SQL SERVER – Online Index Rebuilding Index Improvement in SQL Server 2012

    - by pinaldave
    Have you ever faced situation when you see something working and you feel it should not be working? Well, I had similar moments few days ago. I know that SQL Server 2008 supports online indexing. However, I also know that I cannot rebuild index ONLINE if I have used VARCHAR(MAX), NVARCHAR(MAX) or few other data types. While I held my belief very strongly I came across situation, where I had to go online and do little bit reading from Book Online. Here is the similar example. First of all – run following code in SQL Server 2008 or SQL Server 2008 R2. USE TempDB GO CREATE TABLE TestTable (ID INT, FirstCol NVARCHAR(10), SecondCol NVARCHAR(MAX)) GO CREATE CLUSTERED INDEX [IX_TestTable] ON TestTable (ID) GO CREATE NONCLUSTERED INDEX [IX_TestTable_Cols] ON TestTable (FirstCol) INCLUDE (SecondCol) GO USE [tempdb] GO ALTER INDEX [IX_TestTable_Cols] ON [dbo].[TestTable] REBUILD WITH (ONLINE = ON) GO DROP TABLE TestTable GO Now run the same code in SQL Server 2012 version. Observe the difference between both of the execution. You will be get following resultset. In SQL Server 2008/R2 it will throw following error: Msg 2725, Level 16, State 2, Line 1 An online operation cannot be performed for index ‘IX_TestTable_Cols’ because the index contains column ‘SecondCol’ of data type text, ntext, image, varchar(max), nvarchar(max), varbinary(max), xml, or large CLR type. For a non-clustered index, the column could be an include column of the index. For a clustered index, the column could be any column of the table. If DROP_EXISTING is used, the column could be part of a new or old index. The operation must be performed offline. In SQL Server 2012 it will run successfully and will not throw any error. Command(s) completed successfully. I always thought it will throw an error if there is VARCHAR(MAX) or NVARCHAR(MAX) used in table schema definition. When I saw this result it was clear to me that it will be for sure not bug enhancement in SQL Server 2012. For matter for the fact, I always wanted this feature to be added in SQL Server Engine as this will enable ONLINE Index Rebuilding for mission critical tables which needs to be always online. I quickly searched online and landed on Jacob Sebastian’s blog where he has blogged about it as well. Well, is there any other new feature in SQL Server 2012 which gave you good surprise?

  • Defining Discovery: Core Concepts

    - by Joe Lamantia
    Discovery tools have had a referencable working definition since at least 2001, when Ben Shneiderman published 'Inventing Discovery Tools: Combining Information Visualization with Data Mining'.  Dr. Shneiderman suggested the combination of the two distinct fields of data mining and information visualization could manifest as new category of tools for discovery, an understanding that remains essentially unaltered over ten years later.  An industry analyst report titled Visual Discovery Tools: Market Segmentation and Product Positioning from March of this year, for example, reads, "Visual discovery tools are designed for visual data exploration, analysis and lightweight data mining." Tools should follow from the activities people undertake (a foundational tenet of activity centered design), however, and Dr. Shneiderman does not in fact describe or define discovery activity or capability. As I read it, discovery is assumed to be the implied sum of the separate fields of visualization and data mining as they were then understood.  As a working definition that catalyzes a field of product prototyping, it's adequate in the short term.  In the long term, it makes the boundaries of discovery both derived and temporary, and leaves a substantial gap in the landscape of core concepts around discovery, making consensus on the nature of most aspects of discovery difficult or impossible to reach.  I think this definitional gap is a major reason that discovery is still an ambiguous product landscape. To help close that gap, I'm suggesting a few definitions of four core aspects of discovery.  These come out of our sustained research into discovery needs and practices, and have the goal of clarifying the relationship between discvoery and other analytical categories.  They are suggested, but should be internally coherent and consistent.   Discovery activity is: "Purposeful sense making activity that intends to arrive at new insights and understanding through exploration and analysis (and for these we have specific defintions as well) of all types and sources of data." Discovery capability is: "The ability of people and organizations to purposefully realize valuable insights that address the full spectrum of business questions and problems by engaging effectively with all types and sources of data." Discovery tools: "Enhance individual and organizational ability to realize novel insights by augmenting and accelerating human sense making to allow engagement with all types of data at all useful scales." Discovery environments: "Enable organizations to undertake effective discovery efforts for all business purposes and perspectives, in an empirical and cooperative fashion." Note: applicability to a world of Big data is assumed - thus the refs to all scales / types / sources - rather than stated explicitly.  I like that Big Data doesn't have to be written into this core set of definitions, b/c I think it's a transitional label - the new version of Web 2.0 - and goes away over time.
