    - by KayakJim
    I am working with curlftpfs to mount a remote FTP directory locally in Kubuntu 12.04 64-bit. I have the following entry in my /etc/fstab: curlftpfs#ftp_user:ftp_password@ftp_server /mnt/nimh fuse ro,noexec,nosuid,nodev,noauto,user,allow_other,uid=1000,gid=1000 0 0 I have created the directory in /mnt with the following: |-> ll /mnt total 4.0K drwxrwxr-x 2 jim fuse 4.0K Jan 6 09:56 nimh/ My user does belong to the fuse group as well: uid=1000(jim) gid=1000(jim) groups=1000(jim),27(sudo),105(fuse) I am able to mount manually without issue but then the /mnt changes to: |-> mount /mnt/nimh |-> ll /mnt total 0 drwxr-xr-x 1 jim jim 1.0K Dec 31 1969 nimh/ However when I attempt to umount /mnt/nimh I receive: umount: /mnt/nimh mount disagrees with the fstab My /etc/mtab looks like: curlftpfs#ftp://ftp_user:ftp_password@ftp_server/ /mnt/nimh fuse ro,noexec,nosuid,nodev,allow_other,user=jim 0 0 I am able to umount the filesystem without issue if I sudo.

  • SQL Authority News – Play by Play with Pinal Dave – A Birthday Gift

    - by Pinal Dave
    Today is my birthday. Personal Note When I was young, I was always looking forward to my birthday as on this day, I used to get gifts from everybody. Now when I am getting old on each of my birthday, I have almost same feeling but the direction is different. Now on each of my birthday, I feel like giving gifts to everybody. I have received lots of support, love and respect from everybody; and now I must return it back.Well, on this birthday, I have very unique gifts for everybody – my latest course on SQL Server. How I Tune Performance I often get questions where I am asked how do I work on a normal day. I am often asked that how do I work when I have performance tuning project is assigned to me. Lots of people have expressed their desire that they want me to explain and demonstrate my own method of solving performance problem when I am facing real world problem. It is a pretty difficult task as in the real world, nothing goes as planned and usually planned demonstrations have no place there. The real world, demands real solutions and in a timely fashion. If a consultant goes to industry and does not demonstrate his/her capabilities in very first few minutes, it does not matter how much fame he/she is, the door is shown to them eventually. It is true and in my early career, I have faced it quite commonly. I have learned the trick to be honest from the start and request absolutely transparent communication from the organization where I am to consult. Play by Play Play by Play is a very unique setup. It is not planned and it is a step by step course. It is like a reality show – a very real encounter to the problem and real problem solving approach. I had a great time doing this course. Geoffrey Grosenbach (VP of Pluralsight) sits down with me to see what a SQL Server Admin does in the real world. This Play-by-Play focuses on SQL Server performance tuning and I go over optimizing queries and fine-tuning the server. The table of content of this course is very simple. Introduction In the introduction I explained my basic strategies when I am approached by a customer for performance tuning. Basic Information Gathering In this module I explain how I do gather various information for performance tuning project. It is very crucial to demonstrate to customers for consultant his capability of solving problem. I attempt to resolve a small problem which gives a big positive impact on performance, consultant have to gather proper information from the start. I demonstrate in this module, how one can collect all the important performance tuning metrics. Removing Performance Bottleneck In this module, I build upon the previous module’s statistics collected. I analysis various performance tuning measures and immediately start implementing various tweaks on the performance, which will start improving the performance of my server. This is a very effective method and it gives immediate return of efforts. Index Optimization Indexes are considered as a silver bullet for performance tuning. However, it is not true always there are plenty of examples where indexes even performs worst after implemented. The key is to understand a few of the basic properties of the index and implement the right things at the right time. In this module, I describe in detail how to do index optimizations and what are right and wrong with Index. If you are a DBA or developer, and if your application is running slow – this is must attend module for you. I have some really interesting stories to tell as well. Optimize Query with Rewrite Every problem has more than one solution, in this module we will see another very famous, but hard to master skills for performance tuning – Query Rewrite. There are few do’s and don’ts for any query rewrites. I take a very simple example and demonstrate how query rewrite can improve the performance of the query at many folds. I also share some real world funny stories in this module. This course is hosted at Pluralsight. You will need a valid login for Pluralsight to watch  Play by Play: Pinal Dave course. You can also sign up for FREE Trial of Pluralsight to watch this course. As today is my birthday – I will give 10 people (randomly) who will express their desire to learn this course, a free code. Please leave your comment and I will send you free code to watch this course for free.

  • Dual Control / Four Eyes Principle

    - by Ralf
    I have the requirement to implement some kind of Dual Control or Four-Eyes-Principle, meaning that every change of an object done by user A has to be checked by user B. A trivial example would be a publishing system where an author writes an article and another has to proofread it before it is published. I am a little bit surprised that you find nearly nothing about it on the net. No patterns, no libraries (besides cibet), no workflow solutions etc. Is this requirement really so uncommon? Or am I searching for the wrong terms? I am not looking for a specific solution. More for a pattern or best practice approach.

  • how to evaluate own project

    - by gruszczy
    I am working on a open source project in pure C, that I have started some time ago, but only recently found time to add some features. I can clearly some weaknesses of my old design, so I am trying to refactor my old code. I have no idea however, how to evaluate properly my new code. Do you know about any techniques or tools for code evaluation? I am pretty good with object oriented design, but for about three years I had no contact with purely structural one. Therefore I don't have enough experience, to be able to discern between good and bad design choices.

    I am in the planning stages of a project and am looking to hire a project manager. I want be doing some coding and keeping an eye on all parts of the project but feel a project manager will get better results than I could. I can project manage the project and not code and hire another coder or code myself and hire a project manager. I am worried that the project manager will fell impeded by having the project owner as part of the development team. If I run the project, the team might fall apart causing the project to fail. To stick within budget, I have to be involved in one capacity or another. Does anyone have experience with this situation or suggestions?

  • "SASL authentication failed" with mutt and Gmail, why?

    - by hhh
    I am confused by this, I have installed a lot of new pkgs and followed some tutorials after googling but I keep getting this kind of SASL -err. I am not sure whether the mistake is in some Gmail settings or should I check some settings in Ubuntu? I thought this tutorial here would have solved this problem (i am simply trying to set up local mail reading with mutt, using gmail) but I cannot see the instructed things with telnet: "250-STARTTLS 250-AUTH PLAIN LOGIN" so that is why it is not working. $cat .muttrc set imap_user = "[email protected]" set imap_pass = "pass" #set smtp_url = "smtp://[email protected]:465/" set smtp_url = "smtp://[email protected]:587/" set smtp_pass = "pass" set from = "[email protected]" set realname = "name" set folder = "imaps://imap.gmail.com:993" set spoolfile = "+INBOX" set postponed="+[Gmail]/Drafts" set move = no

  • How can you learn to design nice looking websites?

    - by Richard
    I am a moderately capable web developer. I can put stuff where I want it to go and put some JQuery stuff in there if I need to. However, if I am making my own website (which I am starting to do) I have no idea how to design it. If someone was to sit next to me a point to the screen and say "put this picture there, text there" I can do that quite easily. But designing my own site with my choice of colours and text will look like a toddler has invented it. Does anyone know any websites/books I can look at or has anyone got any tips on the basics of non-toddler web design?

  • Concatenating several .mp3 files into one .mp3

    - by Bakhtiyor
    As it was suggested here I am using cat command to concatenate several .mp3 files into one .mp3 file. Imagine, I have following .mp3 files in the current folder: 001001.mp3 001002.mp3 001003.mp3 001004.mp3 001005.mp3 or, like this: 096001.mp3 096002.mp3 096003.mp3 096004.mp3 I need to concatenate these .mp3 files in there ascending sequence, i.e. 001001.mp3+001002.mp3+001003.mp3+etc. In order to join these .mp3 files into one I am executing following command in the current folder: cat *.mp3 > final.mp3 I tested the final .mp3 file and it is what I am expected, but I need to be sure that above command picks files in there ascending sequence. Can I be sure that above command always concatenates files in the ascending sequence? Thank you Sir!

  • list of things to think about for hosting a potentially high traffic website

    - by SpashHit
    I do my own hosting for a few clients on my own VPS server (Lindode). Since my clients so far have been extremely low traffic, I have not had to really dig into some of the considerations that I would need for a higher traffic site. Now I am bidding on a client whose site will be potentially higher (not Facebook or twitter, but higher than Joe's ice cream shop). Is there a list of things I need to think about that I may be missing? I am going to assume, at least at first, that I will be able to handle them on my shared Linode, but I could move to a dedicated Linode if need be. I am not thinking so far of multiple servers, but short of that there are still considerations. For example, mod_perl instead of straight CGI, better backups, etc. What else? In case it matters, the stack will be debian-linux / apache / Perl / mysql / Template Toolkit.

  • How to familiarize myself with Python

    - by Zel
    I am Python beginner. Started Python 1.5 months back. I downloaded the Python docs and read some part of the tutorial. I have been programming on codechef.com and solving problems of projecteuler. I am thinking of reading Introduction to algorithms and following this course on MIT opencourse ware as I haven't been getting much improvement in programming and I am wasting much time thinking just what should I do when faced with any programming problem. But I think that I still don't know the correct way to learn the language itself. Should I start the library reference or continue with Python tutorial? Is learning algorithms useful for language such as C and not so much for Python as it has "batteries included"? Are there some other resources for familiarization with the language and in general for learning to solve programming problems? Or do I need to just devote some more time?

  • SEO techniques for a complete Flex Website

    - by Bobby Francis Joseph
    I am planning to build a website completely in Flex. All the contents will be static. No DB will be used. Unfortunately I am not building the website for PUMA or NIKE and so SEO is important. There is an overwhelming and confusing information out there about Flex and SEO. The following is a piece of information I found on the web " FLEX( Flash ) uses XML as a primary source of content, and XHTML is just a custom XML. The idea is to to use the HTML pages as XML content for the FLEX( Flash ) application. The XML can be read and indexed by the search engines, and it’s also the ideal content source for your FLEX( Flash ) application.' It goes on to explain how this can be done. Is this really that simple. " Could someone give some credible links. SEO is important for me since I am planning to build the site for a resort.

  • Software jobs after dropping out of masters degree

    - by Bampesh
    I am right now doing my masters in EE in the US, and have previously worked for a couple years in the telecom industry back home in India. I came here wanting to transfer to CS, but at my current university, with my GPA, that seems not very possible. I am not very interested in EE, so I am thinking of dropping out of the program. If I could demonstrate my abilities and experience, would software companies be willing to hire me in the US for my previous experience (with a half completed masters degree). Or would lack of the degree be a huge hindrance? Any suggestions? Thanks

  • DirectX9 dynamic rendering

    - by gardian06
    What I am planning to do is have the models (or maybe just an identifier for the model to be used) stored outside of the directX9 framework, and so in nature have completely dynamic rendering. All of the information that I have found contains static rendering (rendering models that are stored in memory at specific positions) I would like information on how to take a model (or identifier for a model type) that is stored outside of the framework, and render it to the screen. I am expected to take a container that holds all the relevant data to be rendered. The information outside would hold the position, orientation (quaternion, though I am told that I can also get a rotation matrix if I prefer), and dimensions (scale)

  • SQL SERVER – Replace a Column Name in Multiple Stored Procedure all together

    - by pinaldave
    I receive a lot of emails every day. I try to answer each and every email and comments on Facebook and Twitter. I prefer communication on social media as this gives opportunities to others to read the questions and participate along with me. There is always some question which everyone likes to read and remember. Here is one of the questions which I received in email. I believe the same question will be there any many developers who are beginning with SQL Server. I decided to blog about it so everyone can read it and participate. “I am beginner in SQL Server. I have a very interesting situation and need your help. I am beginner to SQL Server and that is why I do not have access to the production server and I work entirely on the development server. The project I am working on is also in the infant stage as well. In product I had to create a multiple tables and every table had few columns. Later on I have written Stored Procedures using those tables. During a code review my manager has requested to change one of the column which I have used in the table. As per him the naming convention was not accurate. Now changing the columname in the table is not a big issue. I figured out that I can do it very quickly either using T-SQL script or SQL Server Management Studio. The real problem is that I have used this column in nearly 50+ stored procedure. This looks like a very mechanical task. I believe I can go and change it in nearly 50+ stored procedure but is there a better solution I can use. Someone suggested that I should just go ahead and find the text in system table and update it there. Is that safe solution? If not, what is your solution. In simple words, How to replace a column name in multiple stored procedure efficiently and quickly? Please help me here with keeping my experience and non-production server in mind.” Well, I found this question very interesting. Honestly I would have preferred if this question was asked on my social media handles (Facebook and Twitter) as I am very active there and quite often before I reach there other experts have already answered this question. Anyway I am now answering the same question on the blog so all of us can participate here and come up with an appropriate answer. Here is my answer - “My Friend, I do not advice to touch system table. Please do not go that route. It can be dangerous and not appropriate. The issue which you faced today is what I used to face in early career as well I still face it often. There are two sets of argument I have observed – there are people who see no value in the name of the object and name objects like obj1, obj2 etc. There are sets of people who carefully chose the name of the object where object name is self-explanatory and almost tells a story. I am not here to take any side in this blog post – so let me go to a quick solution for your problem. Note: Following should not be directly practiced on Production Server. It should be properly tested on development server and once it is validated they should be pushed to your production server with your existing deployment practice. The answer is here assuming you have regular stored procedures and you are working on the Development NON Production Server. Go to Server Note >> Databases >> DatabaseName >> Programmability >> Stored Procedure Now make sure that Object Explorer Details are open (if not open it by clicking F7). You will see the list of all the stored procedures there. Now you will see a list of all the stored procedures on the right side list. Select either all of them or the one which you believe are relevant to your query. Now… Right click on the stored procedures >> SELECT DROP and CREATE to >> Now select New Query Editor Window or Clipboard. Paste the complete script to a new window if you have selected Clipboard option. Now press Control+H which will bring up the Find and Replace Screen. In this screen insert the column to be replaced in the “Find What”box and new column name into “Replace With” box. Now execute the whole script. As we have selected DROP and CREATE to, it will created drop the old procedure and create the new one. Another method would do all the same procedure but instead of DROP and CREATE manually replace the CREATE word with ALTER world. There is a small advantage in doing this is that if due to any reason the error comes up which prevents the new stored procedure to be created you will have your old stored procedure in the system as it is. “ Well, this was my answer to the question which I have received. Do you see any other workaround or solution?

  • going from closed-source to open-source [closed]

    - by mspoerr
    I am thinking of releasing the source code of my application (Freeware at the moment). It is written in C++ with VisualStudio 2008 and all used 3rd-party libs are free or open-source and platform independent. The idea to release the source-code is very old, but till now I did not want to show the code because I am not sure if it is nice/well designed (I am not a professional developer), but the application is growing and help would be very welcome, but I want to keep control... What do I need to consider? Is there any best practice for this scenario? The code itself is one thing, but there is much more like license, documentation, project settings, 3rd party libs, platform (Sourceforge, other?)

  • Developing for iOS on Linux

    I am looking for an engine or library to develop a game for iOS on Linux. High level, low level, GUI, no GUI, does not matter too much. I am really looking for anything. I'm not actually talking about deploying to iOS from Linux or anything like. I just want to do the bulk of the work on Linux, with minimal changes required to run it on iOS. Edit: YES, I do have access to a Mac, but it is limited. So I want to be able to work on the project on my regular Ubuntu box. Also, I am in the paid developer program, so I can deploy to iOS devices from the Mac.
