  • Are today's general purpose languages at the right level of abstraction ?

    - by KeesDijk
    Today Uncle Bob Martin, a genuine hero, showed this video In this video Bob Martin claims that our programming languages are at the right level for our problems at this time. One of the reasons I get from this video as that Bob Martin sees us as detail managers and our problems are at the detail level. This is the first time I have to disagree with Bob Martin and was wondering what the people at programmers think about this. First there is a difference between MDA and MDE MDA in itself hasn't worked and I blame way to much formalisation at a level you can't formalize these kind of problems. MDE and MDD are still trying to prove themselves and in my mind show great promise. e.g. look at MetaEdit The detail still needs to be management in my mind, but you do so in one place (framework or generators) instead of at multiple places. Right for our kind of problems ? I think depends on what problems you look at. Do the current programming languages keep up with the current demands on time to market ? Are they good at bridging the business IT communication gap ? So what do you think ?

  • Slide-decks from recent Adelaide SQL Server UG meetings

    - by Rob Farley
    The UK has been well represented this summer at the Adelaide SQL Server User Group, with presentations from Chris Testa-O’Neill (isn’t that the right link? Maybe try this one) and Martin Cairney. The slides are available here and here. I thought I’d particularly mention Martin’s, and how it’s relevant to this month’s T-SQL Tuesday. Martin spoke about Policy-Based Management and the Enterprise Policy Management Framework – something which is remarkably under-used, and yet which can really impact your ability to look after environments. If you have policies set up, then you can easily test each of your SQL instances to see if they are still satisfying a set of policies as defined. Automation (the topic of this month’s T-SQL Tuesday) should mean that your life is made easier, thereby enabling to you to do more. It shouldn’t remove the human element, but should remove (most of) the human errors. People still need to manage the situation, and work out what needs to be done, etc. We haven’t reached a point where computers can replace people, but they are very good at replace the mundaneness and monotony of our jobs. They’ve made our lives more interesting (although many would rightly argue that they have also made our lives more complex) by letting us focus on the stuff that changes. Martin named his talk Put Your Feet Up, which nicely expresses the fact that managing systems shouldn’t be about running around checking things all the time. It must be about having systems in place which tell you when things aren’t going well. It’s never quite as simple as being able to actually put your feet up, but certainly no system should require constant attention. It’s definitely a policy we at LobsterPot adhere to, whether it’s an alert to let us know that an ETL package has run successfully, or a script that generates some code for a report. If things can be automated, it reduces the chance of error, reduces the repetitive nature of work, and in general, keeps both consultants and clients much happier.

  • odd system name showing up in terminal

    - by sam
    Ive been working on some command line stuff with an external developer through team viewer for work, to interact with th CL i use terminal on OSX, when working with the developer i was always watching what they were doing and i also have all the bash history. Usually upon opening terminal i get something like this Last login: Tue Sep 17 21:33:02 on ttys001 You have mail. unknown-5c:00:00:00:00:00:~ sam$ (note ive replaced some characters in the last line with 00) But today when i opened up terminal and i get this Last login: Mon Oct 21 16:49:35 on ttys000 You have mail. richies-ipad:~ sam$ Note it now says richies-ipad - any idea why this is ? I dont know any one called richie let alone let them have access to my machine. Is this something to be worried about - the fact that someone has enough access to change that ? Also what does the ttys001 part on the first line mean ?

  • Ubuntu getting wrong hostname from DHCP

    - by sam
    When provisioning new Ubuntu Precise (12.04) servers, the hostname they're getting seems to be generated from the DNS search path, not a reverse lookup on the hostname. Take the following configuration BIND is configured with the hostname, and reverse name Normal zone $TTL 600 $ORIGIN srv.local.net. @ IN SOA ns0.local.net. hostmaster.local.net. ( 2014082101 10800 3600 604800 600 ) @ IN NS ns0.local.net. @ IN MX 5 mail.local.net. my-new-server IN A 10.32.2.30 And reverse @ IN SOA ns0.local.net. hostmaster.local.net. ( 2014082101 10800 3600 604800 600 ) @ IN NS ns0.local.net. $ORIGIN 32.10.in-addr.arpa. 30.2 IN PTR my-new-server.srv.local.net. Then DHCPD is configured to hand out static leases based on mac addresses like so subnet 10.32.2.0 netmask 255.255.254.0 { option subnet-mask 255.255.254.0; option routers 10.32.2.1; option domain-name-servers 10.32.2.1; option domain-name "util.of1.local.net of1.local.net srv.local.net"; site-option-space "pxelinux"; option pxelinux.magic f1:00:74:7e; if exists dhcp-parameter-request-list { option dhcp-parameter-request-list = concat(option dhcp-parameter-request-list,d0,d1,d2,d3); } group { option pxelinux.configfile "pxelinux.cfg/pxeboot"; host my-new-server { fixed-address my-new-server.srv.local.net; hardware ethernet aa:aa:aa:bb:bb:bb; } } } So the hostname should be my-new-server.srv.local.net, however when building a Ubuntu 12.04 node, the hostname ends up as my-new-server.util.of1.local.net When building Lucid (10.04) hosts, the hostname will be correct, it's only on Precise/12.04 nodes we have the problem. Doing a normal and reverse lookup on the host and IP returns the correct result Sams-MacBook-Pro:~ sam$ host my-new-server my-new-server.srv.local.net has address 10.32.2.30 Sams-MacBook-Pro:~ sam$ host my-new-server.srv.local.net my-new-server.srv.local.net has address 10.32.2.30 Sams-MacBook-Pro:~ sam$ host 10.32.2.30 30.2.32.10.in-addr.arpa domain name pointer my-new-server.srv.local.net. The contents of the hosts file is incorrect too 127.0.0.1 localhost 127.0.1.1 my-new-server.util.of1.local.net of1.local.net srv.local.net my-new-server So it looks like when it creates the hosts file, it puts the entire contents of the DNS search path into the local address so the FQDN according to the server is the short hostname as defined, then the first domain in the search path. Is there a way to get around this behaviour, or fix this so it gets the hostname correctly? It's picking up the first part of the hostname, then the rest is wrong.

  • Tough Decisions

    - by Johnm
    There was once a thriving business that employed two Database Administrators, Sam and Jim. Both DBAs were certified, educated and highly talented in their skill sets. During lunch breaks these two DBAs were often found together discussing best practices, troubleshooting techniques and the latest release notes for the upcoming version of SQL Server. They genuinely loved what they did. The maintenance of the first database was the responsibility of Sam. He was the architect of this server's setup and he was very meticulous in its configuration. He regularly monitored the health of the database, validated backup files and regularly adhered to the best practices that were advocated by well respected professionals. He was very proud of the fact that there was never a database that he managed that lost data or performed poorly. The maintenance of the second database was the responsibility of Jim. He too was the architect of this server's setup. At the time that he built this server, his understanding of the finer details of configuration were not as clear as they are today. The server was build on a shoestring budget and with very little time for testing and implementation. Jim often monitored the health of the database; but in more of a reactionary mode due to user complaints of slowness or failed transactions. Deadlocks abounded and the backup files were never validated. One day, the announcement was made that revealed that the business had hit financially hard times. Budgets were being cut, limitation on spending was implemented and the reduction in full-time staff was required. Since having two DBAs was regarded a luxury by many, this meant that either Sam or Jim were about to find themselves out of a job. Sam and Jim's boss, Frank, was faced with a very tough decision. Sam's performance was flawless. His techniques and practices were perfection. The databases he managed were reliable and efficient. His solutions are "by the book". When given a task it is certain that, while it may take a little longer, it will be done right the first time. Jim's techniques and practices were not perfect; but effective and responsive. He made mistakes regularly; but he shows that he learns from them and they often result in innovative solutions. When given a task it is certain that, while the results may require some tweaking, it will be done on time and under budget. You are Frank's best friend. He approaches you and presents this scenario. He must layoff one of his valued DBAs the very next morning. Frank asks you: "All else being equal, who would you let go? and Why?" Another pertinent question is raised: "Regardless of good times or bad, if you had to choose, which DBA would you want on your team when tough challenges arise?" Your response is. (This is where you enter a comment below)

  • Exchange ActiveSync with multiple email addresses

    - by Martin Robins
    I have Exchange 2007 SP2, and I have successfully connected my Windows Mobile phone via Exchange ActiveSync and can send and receive emails. I have two addresses within my Exchange mailbox, [email protected] and [email protected], with the second being set as the reply address. When I view my email addresses on my device, I see both of these email addresses, however when I send new messages it always selects the first email address as the reply address and not the second. It is probably worth pointing out that, like in the example provided above, the email addresses are shown alphabetically and the address being selected is the first alphabetically (just in case that matters). I would like to set the device to always select the reply address specified in the mailbox, or at least be able to ensure that the address I want is selected if I have to select it manually on the device, but cannot find any way to make this happen. Can anybody help?

  • Book Review: SSIS Design Patterns

    - by andyleonard
    Samuel Vanga ( Blog | @SamuelVanga ) has posted a review of our new book SSIS Design Patterns at his blog . Several of Sam’s statements struck me, but none more than this: Within a few hours of reading SQL Server 2012 Integration Services Design Patterns , it stood out that none of the authors were trying to impress by showing what they all know in SSIS. Instead, they focused on describing solutions and patterns in a great detail (exactly why I paid for). Sam mentions he could not locate the source...(read more)

  • In SAP Functional a good career path ???

    - by Sam Ahmed
    Hi My name is Sam and I am 23 right know.I have graduated a year back in the domain of computer science.I am currently working as SAP SD consultant and have a project under my belt. Currently working in SAP seems price less as people are dieing for it but at the same time I have really strong academics and many people are forcing me to apply for masters abroad for which I have to leave this job.This decision seems to be really tough. This decision of moving to SAP sometimes makes me happy as it is valuable and on the other hand my technical skills are completey dieing. Most of my accomplishers in my family dont encourage me to be in SAP especially in USA and consider it as a mediocre career. Was my decision right or should I move back to technical and go for MS???

  • Book Review: Professional ASP.NET Design Patterns by Scott Millett

    - by Sam Abraham
    In the next few lines, I will be providing a brief review of Wrox’s Professional ASP.NET Design Patterns by Scott Millett. Design patterns have been a hot topic for many years as developers looked to do more with less, re-use as much code as possible by creating common libraries, as well as make their code easier to understand, extend and collaborate on. Scott Millett’s book covered classic and emerging patterns in a practical presentation that demonstrated with thorough examples how to put each pattern to use in the context of multi-tiered ASP.NET applications. The author’s unique approach and content earned him much kudos in the foreword by Scott Hanselman as well as online reviews. The book has 14 chapters of which 5 are dedicated to a comprehensive case study. Patterns covered therein include S.O.L.I.D, Gang of Four (GoF) as well as Martin Fowler’s Patterns of Enterprise Applications. Many thanks to the Wiley/Wrox User Group Program for their support of our West Palm Beach Developers’ Group. Best regards, --Sam You can access my reviews of books I recently read: Professional WCF 4.0 Inside Windows Communication Foundation Inside Microsoft SQL Server 2008 series

  • Will Tracking Subdomains as Single Entity with Google Analytics Help SEO? [closed]

    - by Sam Gridley
    Possible Duplicate: Does Google Analytics data affect SEO? We have two subdomains, one for our blog and one for our ecommerce store. The blog serves to bring traffic and the store is how we monetize the site. We have them designed to appear as one large site, but I know google sees them as two sites. Here is how the subdomains look: www.example.com (store) blog.example.com (blog) I believe I can configure analytics to use subdomain tracking as explained here: http://support.google.com/googleanalytics/bin/answer.py?hl=en&answer=55524 But my question is whether this will cause google to see our 2 subdomains as one larger domain for SEO purposes. In other words, is there any relationship to how you configure google analytics and how google indexes and ranks your website(s) and pages? Is there anything I need to do in anaytics or webmaster tools to make google aware that these two subdomains work together as one website? Thanks! Sam

  • Identify my terminal session that started a particular process

    - by Sam
    I'm using Gnome on Ubuntu. I often have 8-20 terminal sessions open and in some of them I have su'd to a different user. The specific problem that caused me to write this query happens when using git status, but this is more general issue. git status will tell me I have an uncontrolled file .foo.java.swp. This means that in one of my terminal sessions I have vi open on foo.java. I need a script or tool that would tell me in which terminal session that vi is running. I can do a "ps aux | grep vi" to pretty easily find the pid of the particular vi. It would be nice if the tool highlighted the terminal on my task bar in some way. Thanks. -Sam

  • Application won't run when installed in "/opt"

    I've developed a program for the App Developer Showdown, with quickly, in python, and it works as expected when I package and install it normally -in /usr. However when packaged for installation in /opt it doesn't run -and I'm not getting (or can't find) an error message of any sort, as to what the problem might be. I was wondering if someone here has the answer. The app does require root access -using gksudo- to function. I'm fairly new to programming, but not to Linux.

  • How can I get a 1920x1080 resolution?

    - by Sam T.
    I a newbie Linux and have just installed Ubuntu in a dual boot with Windows 7. I love the interface of Ubuntu but unfortunately I can only get a 800x600 or 1024x728 resolution with black bars all around the screen. I have an nVidia GTX 570 graphics card and an Asus 1080p 23" monitor. What may be of note is that I had to use the nomodeset command on installation of the boot would get stuck at a line with "nouveau", which I understand is to do with the drivers. Additionally, when I type in xrandr to the terminal, it comes up with the error message "failed to get size of gamma for output default". I guess what I am looking for here is someone who could explain to me really simply the steps I have to take to get a full 1080p resolution, at which point I am sure i will become a great fan of the OS! Thanks in advance, Sam T.

  • Why Does DreamWeaver CS5 Discriminate between File Extensions, Even After Modding Mime Types!?

    - by Sam
    Hi folks, Even After I forced DreamWeaver CS5 to allow opening of .ast extensions as a MIME type of php5, which DreamWeaver now opens and colors correctly as described here, I still have trouble figuring out why it still discriminates between the two file extensions! Symptoms: External Files & Design View I have a file foo.php which php includes other files (e.g. the php-combined css.php and js.php). Now, when opening foo.php all functions work perfectly: the external (included) php files are all recognised correctly. However, when I change foo.php foo.ast, and open it again, It does not recognise the files extensions anymore in the top bar. Also, I lose the Design / Live View functionality.** When I change foo.ast to foo.php, all works again! Anyone any clues of why there remains a a difference between one and other extension? Note1: I have added the .ast extension to these four files, next to .php: 1 C:\Users\Sam\AppData\Local\VirtualStore\Program Files (x86)\Adobe\Adobe Dreamweaver CS5\configuration\DocumentTypes\MMDocumentTypes.xml 2 C:\Program Files (x86)\Adobe\Adobe Dreamweaver CS5\configuration\DocumentTypes\MMDocumentTypes.xml 3 C:\Users\Sam\AppData\Roaming\Adobe\Dreamweaver CS5\en_US\Configuration\Extensions.txt 4 C:\Program Files (x86)\Adobe\Adobe Dreamweaver CS5\configuration\Extensions.txt Note2: sometimes, even .php files do not want to show in design view or live view. Could this be caused by a corrupted installation?

  • Sharing code in LGPL and proprietary software

    - by Martin
    Hi I'm working on a piece of software that'll be released as a dll under LGPL. The software interfaces with hardware from a small company that has provided me with the needed libraries and some code to use them correctly (not only headers but its all in a separate file). As far as i know, the same code is used in their proprietary software that they don't intend to open source but they'd be fine releasing the piece of code they've given me. Now here's the question: What license could be used on the code I got from the company? I guess using GPL or LGPL would make them violate GPL when using the same code in their other software. Is MIT a good idea? Is it ok to just include a file with MIT license on it in my otherwise LGPL:ed project? Since I'm not the copyright holder, I'd have to ask the company to apply the license obviously but that shouldn't be a problem. Thanks /Martin

  • Can I perform a distribution upgrade without rebooting?

    - by Martin Eve
    Hi, I would, ideally, like to run a distribution upgrade that doesn't end in a complete reboot of the machine (owing to an irritation in my hardware that requires a period of disconnection from the power supply before my SSD can be detected). What would be the procedure for doing this from a desktop environment? I would image: dist-upgrade shutdown all graphical services restart X I'd appreciate any advice (particularly on the exact procedure for step 2, if this correct). NB. I'm using KSplice for in-memory kernel patching, so the kernel is already dealt with. Many thanks, Martin

  • Open source engagement as a professional reference

    - by Martin
    if one commits his or her time to an open source project, he or she may be invest a substantial amount of time without getting paid. As much as altruism is appreciable, I wonder whether it "counts" as an activity which can be shown and is valued in job applications. If the company is worth your time and working power, which it should be in my honest opinion. So I wonder whether there is something like a common practice in open source projects for this matters. Say, something like Mr. Martin has been working on our project for five years and has contributed this and that,[...] I we wish him very best for his future. Mr. ChiefofProject I think this is a just concern. Do have experiences you can share?

  • msvsmon is locking up my pdbs

    - by Sam Saffron
    During developement of my media center plugin (which has a few custom build steps to gac stuff and such) msvsmon has a rather annoying behaviour. First compilation usually goes well, but subsequent compilations complain about myplugin.pdb being locked Error 1 Unexpected error creating debug information file 'C:\Users\sam\source\myfile.PDB' -- 'C:\Users\sam\source\obj\Debug\myfile.pdb: The process cannot access the file because it is being used by another process. If I exit VS and nuke the object directory, I am able to compile again. Also, if I kill off msvsmon.exe I am able to compile again (but can not debug) Has anyone seen this error? Are there any workarounds? I already disabled live semantic errors, just in case.

  • Book Review: &ldquo;Inside Microsoft SQL Server 2008: T-SQL Querying&rdquo; by Itzik Ben-Gan et al

    - by Sam Abraham
    In the past few weeks, I have been reading “Inside Microsoft SQL Server 2008: T-SQL Querying” by Itzik Ben-Gan et al. In the next few lines, I will be providing a quick book review having finished reading this valuable resource on SQL Server 2008. In this book, the authors have targeted most of the common as well as advanced T-SQL Querying scenarios that one would use for development on a SQL Server database. Book content covered sufficient theory and practice to empower its readers to systematically write better performance-tuned queries. Chapter one introduced a quick refresher of the basics of query processing. Chapters 2 and 3 followed with a thorough coverage of applicable relational algebra concepts which set a good stage for chapter 4 to dive deep into query tuning. Chapter 4 has been my favorite chapter of the book as it provided nice illustrations of the internals of indexes, waits, statistics and query plans. I particularly appreciated the thorough explanation of execution plans which helped clarify some areas I may have not paid particular attention to in the past. The book continues to focus on SQL operators tackling a few in each chapter and covering their internal workings and the best practices to follow when used. Figures and illustrations have been particularly helpful in grasping advanced concepts covered therein. In conclusion, Inside Microsoft SQL Server 2008: T-SQL Querying provided me with 750+ pages of focused, advanced and practical knowledge that has added a few tips and tricks to my arsenal of query tuning strategies.
