  • Can I manually map a file extension to an IFilter?

    - by Deane
    I'm working with Microsoft Indexing Service. I have purchased a third-party IFilter to extract XMP metadata from Adobe products. I'm having trouble getting it to work, and it occurs to me that the problem is that I don't actually have the Adobe software installed on my server, so the IFilters are not mapped. Put another way, there's nothing to tell the indexer that ".psd" files should use this DLL rather than the default DLL. Is it possible to manually map file extensions to the IFilter you want to use?

  • VMware Virtualisation - Convert 64bit Windows Server to 32bit VM?

    - by dannymcc
    I have just started playing around with Vmware sphere and have the hypervisor OS installed on a spare HP ProLiant DL360 G4. I have created a test virtual machine running Ubuntu which has worked well. As a test project I wanted to convert a powered on server running Windows Server 2008 64bit into a virtual machine. As soon as I ran the Vmware Go software to start the conversion it became apparent that I cannot run 64bit guest OS's on that particular server. So, is there a way of migrating 64bit to 32bit during the conversion?

  • Switching to a career in Machine Learning

    - by Naive Machine Learner
    My day job is plain old software development. I am also doing my Masters in CS (part time, course based). I took a course on AI and found machine learning quite fascinating but like most courses it only offered a basic intro. I intend to learn more about Machine Learning and if possible get a job in that field. When I look at job postings in this field it is clear that a Phd in Machine learning (or prior experience in the field with considerable expertise) is required for most of them. I'm looking for advice on self learning to gain experience that'll useful in industry. At least, enough experience to get my foot in. I will do the obvious ones like reading text books, papers etc. Perhaps any open source efforts that I can participate in or something I could do on my own? Apologies if I'm being vague here but I hope there are at least a few of you who done a similar switch and can advise. Thanks !

  • Eclipse on mac: how comes that everytime I install an Eclipse plug-in on my mac I always get this er

  • Did you forget me?

    - by Ratman21
    I know it has been a long time since I last blogged. Still at it, looking for work in the “IT” field. Had another phone interview (only found out during the interview that it was for one year contract job, but I still would take it) for a Help Desk job. Didn’t get it, they thought I was not a application support person and more of a hardware support. Gee..I started out in “IT” as a programmer. Then a programmer/computer operator, then a Tandem/Lan operator and finally a Network operator. I had to deal with so many different operating systems, software and applications.   And they thought I was too hardware. Well I am working a temp day job with the U.S. Census. It gets me out of the house and out in the country. If find getting paid to check for living quarters not bad job, except for the many houses I find that are up for sale and looks like it was not the owners (former owners it seems) idea, with the kids toys still in the yards. Not good for some one with a over active imagine or for my truck. So far I have backed in to ditch (and had to be pulled out), in to power pole (no damage to pole and very little to truck) and a mail box (no damage to truck but mail box was leaning a little) in the last two weeks.   Oh an I have started reading/using “The Love Dare” book from the movie “Fireproof”. I restarted (yes I have had to go back to day one from day five) the dare this Sunday. Dare one dare/day one “Love Is Patient” and the first dare is (reading from the book is): “The first part of this dare is fairly simple. Although Love is communicated in a number of ways. Our words often reflect the condition of our heart. For the next day, resolve to demonstrate patience and to sys nothing negative to your spouse at all. If the temptation arises, choose not to say anything. It’s better to hold your tongue that to say something you’ll regret. “. This was almost too easy as I can hold back from saying anything bad to any one but, this can also be a problem in life (you hold back for so long and!!!!!!!!!!!!!! Boom). Check back for dare/day two “Love Is Kind”.

  • quick folder access on Linux (akin to Launchy)

    - by Eli Bendersky
    Launchy is a great piece of software, I use it on Windows mainly for quickly accessing folders. I love its auto-indexing in the background, and hardly ever browse through folders manually these days, solves me lots of time. On Linux (Ubuntu 9.10), I usually "live" in the terminal, however. Therefore, Launchy on Linux (or Gnome Do, or its other replacements) are not what I need - as it opens the file manager, and I don't need the file manager. What I do need is something that indexes my folders and lets me cd into them quickly in the terminal. For example: mycd python_c Will cd to: ~/dev/scripts/python_code I hope my intention is understood :-) Are you familiar with such tools?

  • Shell Script Launching Child Processes

    - by Matt James
    Disclaimer: I'm totally new to shell scripting, but have quite a bit of experience in other languages like PHP and Obj-C. I'm writing my first daemon script. Here are the goals: I want it to run in the background I want it to be triggered by an init.d script that includes start/stop/restart commands I want each process in a loop to trigger its own subprocess. When the parent process kicked off by the init.d script is killed, I want the subprocesses to die as well. Essentially, I'm looking for the same kind of behavior that appears to be very common among software like apache, spamd, dovecot, etc. But, based on my research, I haven't found a single, simple answer as to how this kind of thing is achieved. Any help is greatly appreciated.

  • Citrix Secure Gateway not redirecting to login URL

    - by Dave
    We have an older setup for XenApp - users log in through Citrix Secure Gateway running on a windows box. (We hope to start using a NetScaler soon.) Earlier today, connections to https://citrix.company.com/ starting throwing up a 503 error page, instead of redirecting to https://citrix.company.com/Citrix/XenApp/ If you go directly to the /Citrix/Xenapp/ URL, the user is properly directed to the login page, and can launch apps. We've restarted the service, and rebooted the server. We haven't yet tried uninstalling and reinstalling the software. Before we do this, I'm looking for ideas as to how we can get the redirect working again without a fairly major outage window. To make things more interesting, many of our users have Citrix Receiver installed, also pointed at https://citrix.company.com/. Receiver makes itself the default launcher for ICA files, and gives a connection error when it tries to load apps - probably because of the same non-functional rediect?

  • ubuntu 12.04 copy whole server

    - by Jiechao Li
    all. My company host all the software, including application and website in one local ubuntu server. But recently we start to use Amazon EC2, and want to move the whole server to cloud. Is there anyway to copy the entire server to EC2? OS is the same, ubuntu 12.04, and just one server, and one user account. On EC2 is also one instance, one account. I don't know whether there is a simple and quick way to do that. Thanks a lot!!

  • Standalone firewall + antivirus or combined security tools?

    - by pukipuki
    For years I'm using some antivirus software and different firewall. Now every antiviruses have got some firewall features and there are complete "internet security" complexes... and every firewall get some antivirus functionality and there are "internet security" versions. Firstly, it is hard and sometimes impossible to install and use standalone AV and FW. Sometimes I can't avoid them (i can't install KAV2010 without removing Outpost firewall etc). Secondly, complex solutions have some disbalance. Farewall from famous antivirus-brand is so user-friendly that is not suitable for me (lack of details in Norton Internet Security for example) and antiviruses from famous firewall-brands are still weak, it is proved by tests. What is today best-practices in case of functionality and security?) Some internet-security complex or two standalone applications from different vendors?

  • How does a PDF prevent itself from being printed?

    - by Steven
    I have a PDF for my camera's manual, and Adobe Reader won't let me print it (the print option is grayed out). SumatraPDF also does the same thing (it even says print denied). How does the PDF prevent itself from being printed? It seems that if the program can display it on the screen, then it can also print it. Maybe Adobe Reader respects the PDF not printing, but surely an open source PDF reader wouldn't be so restrictive. So is there something more to this than merely the PDF reader software respecting the PDF's request to not be able to be printed?

  • Project Manager that wants to lock in time estimate with a signed contract

    - by sunpech
    At a previous employment, a project manager (PM) wasn't satisfied with the delivery time of the code on a project I was on. I was told by my project lead that that the PM was considering having me sign a contract to lock-in my time estimates I gave for tasks and delivery dates. The situation on the project was that we were working with new technologies, codebase, coding standards, and very prone-to-change requirements. I was learning new things and applying them the best I could on requirements that kept on changing. The requirements throughout the iterations grew by 2-3 times, with my estimate-to-complete growing by roughly 5-8 times. The only things that didn't change were the estimates and delivery dates. Yes, I did end up missing most deadlines. And I was working on some very new technologies that no one else on the entire development team could really help out on because they wouldn't be familiar with it. At least not easily. It seemed to me then, that the PM wanted his numbers to add up-- and thus wanted me to sign a contract to "ensure" that I would always deliver working code on time. I suppose with a signed contract the PM could use it against me if I couldn't deliver on time. I believe what happened next was that other project managers and/or project leads defended me, and didn't let this happen. My question is, should this raise a red flag about the manager? Is it common practice for a manager to lock-in time estimates of a software developer with a signed contract? Or in this case, try to. Please note, I was a full time employee, not an independent consultant. Update: I want to add that I did give new estimates weekly, but it seems the original estimates and delivery dates were what the PM was fixated on.

  • How do I make complex SQL queries easier to write?

    - by DragonLord
    I'm finding it very difficult to write complex SQL queries involving joins across many (at least 3-4) tables and involving several nested conditions. The queries I'm being asked to write are easily described by a few sentences, but can require a deceptive amount of code to complete. I'm finding myself often using temporary views to write these queries, which seem like a bit of a crutch. What tips can you provide that I can use to make these complex queries easier? More specifically, how do I break these queries down into the steps I need to use to actually write the SQL code? Note that I'm the SQL I'm being asked to write is part of homework assignments for a database course, so I don't want software that will do the work for me. I want to actually understand the code I'm writing. More technical details: The database is hosted on a PostgreSQL server running on the local machine. The database is very small: there are no more than seven tables and the largest table has less than about 50 rows. The SQL queries are being passed unchanged to the server, via LibreOffice Base.

  • Why are Linux-based operating systems considered safer than Windows?

    - by echoblaze
    I hear that Linux-based systems are better for security. Apparently they don't have viruses and do not need antivirus software. Even my university claims this - they refuse to have Windows on their servers, which is a real shame because we wanted to use the .NET framework to create some websites. The only reason I can see Linux being safer is because it's open-source, so bugs theoretically would get caught and fixed sooner. I know a bit about how operating systems work, but haven't really delved into how Linux and Windows implement their OS. Can someone explain the difference that makes Linux-based systems more secure?

  • Application Lifecycle Management Tools

    - by John K. Hines
    Leading a team comprised of three former teams means that we have three of everything.  Three places to gather requirements, three (actually eight or nine) places for customers to submit support requests, three places to plan and track work. We’ve been looking into tools that combine these features into a single product.  Not just Agile planning tools, but those that allow us to look in a single place for requirements, work items, and reports. One of the interesting choices is Software Planner by Automated QA (the makers of Test Complete).  It's a lovely tool with real end-to-end process support.  We’re probably not going to use it for one reason – cost.  I’m sure our company could get a discount, but it’s on a concurrent user license that isn’t cheap for a large number of users.  Some initial guesswork had us paying over $6,000 for 3 concurrent users just to get started with the Enterprise version.  Still, it’s intuitive, has great Agile capabilities, and has a reputation for excellent customer support. At the moment we’re digging deeper into Rational Team Concert by IBM.  Reading the docs on this product makes me want to submit my resume to Big Blue.  Not only does RTC integrate everything we need, but it’s free for up to 10 developers.  It has beautiful support for all phases of Scrum.  We’re going to bring the sales representative in for a demo. This marks one of the few times that we’re trying to resist the temptation to write our own tool.  And I think this is the first time that something so complex may actually be capably provided by an external source.   Hooray for less work!

  • Should certain math classes be required for a Computer Science degree?

    - by sunpech
    For a Computer Science (CS) degree at many colleges and universities, certain math courses are required: Calculus, Linear Algebra, and Discrete Mathematics are few examples. However, since I've started working in the real world as a software developer, I have yet to truly use some the knowledge I had at once acquired from taking those classes. Discrete Math might be the only exception. My questions: Should these math classes be required to obtain a computer science degree? Or would they be better served as electives? I'm challenging even that the certain math classes even help with required CS classes. For example, I never used linear algebra outside of the math class itself. I hear it's used in Computer Graphics, but I never took those classes-- yet linear algebra was required for a CS degree. I personally think it could be better served as an elective rather than requirement because it's more specific to a branch of CS rather than general CS. From a Slashdot post CS Profs Debate Role of Math In CS Education: 'For too long, we have taught computer science as an academic discipline (as though all of our students will go on to get PhDs and then become CS faculty members) even though for most of us, our students are overwhelmingly seeking careers in which they apply computer science.'

  • Linksys WRT54Gx as Repeater Bridge

    - by Robert Koritnik
    I have a Linksys WRT54Gx router with DD-WRT software working fine. But. Is it possible to use it as a Repeater Bridge when the host router isn't configured to be in the default 192.168.1.1 subnet? I've set everything from these instructions. I've also tried setting repeater router's IP address to be inside host's subnet, setting Gateway + DNS IP addresses... But It still didn't work. Client machines connecting to second router (my Linksys) were configured to use DHCP and also static IPs within host's subnet. Nothing worked. Can anyone tell me how to configure it to make it work?

  • How to start a task before networking?

    - by user1252434
    I've written an upstart task that modifies /etc/network/interfaces. (Actually a file sourced into it.) Which start on condition do I need to declare to let my task run before any networking jobs? I've tried start on starting networking, but that's apparently too late. When I log in after booting I can see that the changes were written, but obviously they are not used: the new config states a static IP, but the boot process waits for a non-existing DHCP server (old config) to time out. I've also tried start on starting network-interface INTERFACE=eth0, which didn't work either. IIRC there was an error in the log that the change couldn't be written. Background: I need a VM template that can be cloned and the clones configured through a script. Among other settings, I need to give them a static IP address to access them from the host. I use guestfish to write a config file to one of the virtual disks and let a script apply these settings to the system. I don't want that disk to contain an actual system settings file. I can't modify /etc directly, because that disk is shared (copy-on-write/diff) among the clones and guestfish apparently doesn't support that type of image. I could also let them use DHCP and setup a server that assigns IP by MAC, but I'm afraid of the complexity. I could also add just another virtual disk for configuration files, but if possible I'd prefer to store settings directly on the system disk image. Used software: Ubuntu Server 12.04, VirtualBox.

  • Advantages of multiple SQL Server files with a single RAID array

    - by Dr Giles M
    Originally posted on stack overflow, but re-worded. Imagine the scenario : For a database I have RAID arrays R: (MDF) T: (transaction log) and of course shared transparent usage of X: (tempDB). I've been reading around and get the impression that if you are using RAID then adding multiple SQL Server NDF files sitting on R: within a filegroup won't yeild any more improvements. Of course, adding another raid array S: and putting an NDF file on that would. However, being a reasonably savvy software person, it's not unthinkable to hypothesise that, even for smaller MDFs sitting on one RAID array that SQL Server will perform growth and locking operations (for writes) on the MDF, so adding NDFs to the filegroup even if they sat on R: would distribute the locking operations and growth operations allowing more throughput? Or does the time taken to reconstruct the data from distributed filegroups outweigh the benefits of reduced locking? I'm also aware that the behaviour and benefits may be different for tables/indeces/log. Is there a good site that distinguishes the benefits of multiple files when RAID is already in place?

  • wget works with company proxy but apt-get and dpkg doesn't

    - by damian
    Hi, I am trying to install some software in a fresh install of Linux dnoseda 2.6.32-21-generic #32-Ubuntu SMP Fri Apr 16 08:10:02 UTC 2010 i686 GNU/Linux. I already set the variables http_proxy, https_proxy and ftp_proxy and wget works perfectly. But when I try with apt-get it blocks trying to conect directly to the site, without the proxy. Or the other behavior that I got is a lots of 407 authentication errors. But the wget of those packages works perfectly. It's something missing? Can you help me? thanks in advance.

  • Windows 2000 Inaccessible Boot Device

    - by Foo_Chow
    I am working with a machine that had its motherboard die. The machine is running Windows 2000 for legacy software. After the motherboard died I used disk2vhd to perform a physical to virtual transfer. The drive data seemed to copy over to the vhd file well. However, whenever i try to boot I get a message saying Inaccessible Boot Device So far I have tried several things to fix it. fixMBR fixBoot chkdsk windows 2000 automated repair Also, I have attempted to open the registry of the vhd without any success. There is another fix that i have seen suggested that requires editing the registry. Is it possible to open a Windows 2000 hive in another OS or another copy of Windows 2000? One other thing to note is that the error appears in all of Virtual PC 2007, Hyper-V and VMWare Player. Does anyone know how to get past this?
