• Linux and GEForge 8400 dual monitor

  - by Andrea Polci

  I'm trying to install a linux distribution on my PC. I have a GEForce 8400 GS with two connected monitors. I tried with fedora 12 and ubuntu 9.1 (both 64 and 32 bit) and the live cd cannot boot properly. I don't get a visible error on ubuntu, it simply hang up during the boot. With fedora I get this erro: [drm] Modeset on unsupported output type [drm] Table 0x0000 not found for 1/1 using first I tried to disconnect one of the two monitor and was able to install on my HD and boot from there, but if I try to connect the second monitor again I cannot boot. Have I to install something else? (a driver for my video card for example).

• What is the correlation between programming language and experience/skills of their users?

  - by Petr Pudlák

  I'm sure there is such a correlation, because experience and skill leads good programmers to picking languages that are better for them, in which they're more productive, and working in a language forms how programmers think and influences their methods and skills. Is there any research or some statistical data of this phenomenon? Perhaps this is not a purely academic question. For example, if someone is starting a new project, it could be worth considering a language (among other criteria of course) for which there is a higher chance of finding or attracting experienced programmers. Update: Please don't fixate on the last paragraph. It's not my intention to choose a language based on this criterion, and I know there are other far more important ones. My interested is mostly academic. It comes from the (subjective) observation and I wonder if someone has researched it a bit. Also, I'm talking about a correlation, not about a rule. Sure there are both great and terrible programmers in every language. Just that in general it seems to me there is a correlation.

• How can I free files that are in use by quicklook?

  - by alex-auguste1

  I have a couple pictures I was looking through and deleting stuck in my trash (Mac OSX 10.6 latest) and finder tells me they are in use when I try to delete them. I looked around online and found the lsof command in terminal (type lsod with a space, drag the file onto terminal, press enter) it told me the file was in use by: COMMAND PID FD Finder 7747 txt Finder 7747 13r mdworker 8685 txt quicklook 8822 13r quicklook 8822 14r any idea what I can do about this? (other than restarting, this happens to me quite a bit), I'm wondering if this could be a bug as well. Thanks for any help.

• Clustering in GlassFish with DCOM on Windows 7

  - by ByronNevins

  I've discovered that Windows 7 makes it very difficult to use DCOM and, mainly, the GlassFish clustering commands that rely on DCOM.  I spent a few days trying to solve the problems.  I don't yet have a cookbook for making DCOM work on Windows 7.  But here are a few tips and advice I've found. run asadmin setup-local-dcom -- It now comes automatically with the open source GlassFish 4.  It will write some critical registry entries for you.  run asadmin validate-dcom to test dcom 3.   When I ran validate-dcom on my Windows 7 network I saw the problem below: Successfully resolved host name to: gloin/10.28.51.10 Successfully connected to DCOM Port at port 135 on host gloin. Successfully connected to NetBIOS Session Service at port 139 on host gloin.Successfully connected to Windows Shares at port 445 on host gloin.Can not access the remote file system.  Is UAC on? : Access is denied. I discovered the actual problem is that Windows 7 no longer has the "C$" Administrative file share available by default. If "C$" isn't available then nothing will work. Here is how to expose the "C$" share: Registry Change -- this change allows “C$” to be accessed.  As soon as I set it -- the file copying started working!  [1] regkey: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System create this key, 32 bit word, with value == 1 LocalAccountTokenFilterPolicy 4.  Turn on the Remote Registry Service -- This is critical and it's easy to do. Windows 7 has it turned off by default. MyComputer-right click, manage, services, then turn on Remote Registry Service and set it to start automatically in the fture. 5. Turn off UAC: %systemroot%\system32\UserAccountControlSettings.exe 6. This is where I discovered that McAfee virus scanner blocks all the NetBios shares!  It has to be disabled.

• How do "custom software companies" deal with technical debt?

  - by andy

  What are "custom software companies"? By "custom software companies" I mean companies that make their money primarily from building custom, one off, bits of software. Example are agencies or middle-ware companies, or contractors/consultants like Redify. What's the opposite of "custom software companies"? The oposite of the above business model are companies that focus on long term products, whether they be deployable desktop/mobile apps, or SaaS software. A sure fire way to build up technical debt: I work for a company that attempts to focus on a suite of SaaS products. However, due to certain constraints we sometimes end up bending to the will of certain clients and we end building bits of custom software that can only be used for that client. This is a sure fire way to incur technical debt. Now we have a bit of software to maintain that adds nothing to our core product. If custom work is a sure fire way to build technical debt, how do agencies handle it? So that got me thinking. Companies who don't have a core product as the center of their business model, well they're always doing custom software work. How do they cope with the notion of technical debt? How does it not drive them into technical bankruptcy?

• Presario r3000 hangs on boot to Ubuntu 12.04

  - by Chris

  I have a Compaq Presario r3000 laptop with Ubuntu 12.04 32 bit. 1.2GB RAM, with a nvidia Gforce 420 Go with 32MB RAM. It hangs on bootup about 3 out of 4 times at either the purple screen, or with a cursor in the upper left corner. Booting without a splash screen shows it hanging after attempting to initialize the floppy controller. Unity has never booted to 3D either, only 2D, with the additional drivers always failing to install. I searched all over this board and found similar issues, and tried everything there. Extensive vid driver install and uninstalls. Network issues that I've since resolved. I even found a very similar topic with a fix that didn't work. I'll probably try a clean install today (given how much I've probably messed up), and I would really appreciate any ideas. I'm fairly new to Ubuntu, so if you would like to see any error logs or configs, please walk me through exactly how to get and post them here. Thanks.

• What You Said: Desktop vs. Web-based Email Cients

  - by Jason Fitzpatrick

  We clearly tapped into a subject you all have a strong opinion about with this week’s Ask the Readers post; read on to see how your fellow readers manage their email on, off, and across desktops and devices. Earlier this week we asked you to share your email workflow and you all responded in force. TusconMatt doesn’t miss desktop clients one bit: Switched to Gmail years ago and never looked back. No more losing my emails and contacts if my HDD crashes or when I reinstall. No more frustration with not being able to access an email on the road because it downloaded to my drive and deleted from the server. No more mailbox full messages because I left messages on the server to avoid the above problem! I love having access to all emails from anywhere on any platform and don’t think I could ever go back to a dedicated email client.

• Version control and branching when using Oracle

  - by Ed Woodcock

  Hi folks: At work we're using Oracle and C#/ASP.net to handle a customer's website, this site is very large-scale so the database is very large. We use Perforce for our version control, and tack create or replace scripts to FogBugz cases whenever a database change, which has been fine until now, as we are now at a point where five developers are working on five expansions for the system, each on a seperate Perforce branch. Unfortunately, we cannot get duplicate databases, due to the database size, so everyone is still working from the same one. This is obviously a cause of problems: only ten minutes ago we had a bit of an issue where a stored procedure change for a branch propagated over to the Pre-Production server and caused a large number of crashes for the testers. Ideally, we would like a way to track these changes without having to manually keep track of them through FogBugz. My question is: how do you lot handle this situation? I'm sure there must be a good way by now to handle versioning, or at least tracking changes, in an Oracle database.

• Is it possible to use Sharepoint 2007 without installing it?

  - by foxtrot

  Hi there! My company wants to buy Sharepoint 2007 and they asked me if I could give an opinion. I've saw already a lot of videos and read e-books but would like to use it for a while, specially the integration with Sharepoint Designer 2007. The only way to do that is installing it on a trial basis? Is there any other way? Any available public installation? I only have an old 32-bit laptop with Windows XP. Thanks in advance!

• What are the best ways to professionally increase your online presence?

  - by Rob S.

  I've been hunting around the job market for a little bit now and I've been shocked by some of the things I am seeing. Software developers who make themselves more "known" online are getting far more and far better positions than people competing against them who are not as well "known" online. After doing some reading on the subject I realized that I actually shouldn't be so shocked by this. We are living in the most fast paced era of mankind and employers want to be able to learn as much as they can about a potential employee before they hire them. The easier we as software developers make it for us to be found it seems the better are chances of landing that dream job become. In some cases, employers are even finding us instead of us applying to them. So what are some of the best ways for me as a software developer to increase my online presence? I already hang around stack exchange sites such as programmers and stack overflow increasing my rep whenever I can. I maintain many open source projects as both a committer and project owner on Google Code and Github. I have a Twitter account, a website, and a blog. What else can I do to give myself a bigger online presence? Additionally, are there any good do's and don'ts for handling your web presence? Bashing your employer is an obvious don't but I'm interested in everything from the most basic to most subtle suggestions to give yourself a more appealing online presence. Thank you very much in advance for your time.

• Real world pitfalls of introducing F# into a large codebase and engineering team

  - by nganju

  I'm CTO of a software firm with a large existing codebase (all C#) and a sizable engineering team. I can see how certain parts of the code would be far easier to write in F#, resulting in faster development time, fewer bugs, easier parallel implementations, etc., basically overall productivity gains for my team. However, I can also see several productivity pitfalls of introducing F#, namely: 1) Everyone has to learn F#, and it's not as trivial as switching from, say, Java to C#. Team members that have not learned F# will be unable to work on F# parts of the codebase. 2) The pool of hireable F# programmers, as of now (Dec 2010) is non-existent. Search various software engineer resume databases for "F#", way less than 1% of resumes contain the keyword. 3) Community support as of now (Dec 2010) is less available. You can google almost any problem in C# and find someone that has already dealt with it, not so with F#. Third party tool support (NUnit, Resharper etc) is also sketchy. I realize that this is a bit Catch-22, i.e. if people like me don't use F# then the community and tools will never materialize, etc. But, I've got a company to run, and I can be cutting edge but not bleeding edge. Any other pitfalls I'm not considering? Or anyone care to rebut the pitfalls I've mentioned? I think this is an important discussion and would love to hear your counter-arguments in this public forum that may do a lot to increase F# adoption by industry. Thanks.

• The Middle of Every Project

  - by andrew.sparks

  I read a quote somewhere “The middle of every successful project looks like a mess.” or something to that effect. I suppose the projects where the beginning, middle and end are a mess are the ones you need to watch out for. Right now we are in ramp up of the maintenance/support teams at a big project in the Nordics. We are facing a year of mixed mode operations, where we have production operations and the phased rollout to new locations in parallel. The support team supports, and the deployment team deploys. As usual the assumption right up to about a month or so before initial go-live was that the deployment team would carry the support. Not! Consequently we had a last minute scramble over the Christmas/New Year to fire up a support/maintenance team. While it is a bit messy and not perfect – the quality of the mess (I mean scramble) is not so bad. Weekly operational review with the operational delivery managers, written issue lists and assigned actions, candid discussions getting the problems on the table and documented, issues getting solved and moved off the table. So while the middle of a project might look like a mess (even the start) it is methodical use of project management tools of checklists and scheduled communication points that are helping us navigate out of the mess and bring it all under control.

• Can't install Parallels Tools on Debian 7.2.0

  - by jfm429

  (Parallels Desktop 9, latest version) As per instructions, I switch to root: $ su - root $ whoami root $ echo $EUID 0 and then execute the installer: $ cd /media/cdrom0 $ ./install and I get this error: sudo: unable to execute ./install: Permission denied What? I'm root! What's with this? I double check to make sure the execute bit is set: $ ls -lA | grep install$ -r-xr-xr-x 1 root root 17284 Oct 25 09:22 install Yep. People online are saying that you need to drag the install script to the terminal after typing sudo. So I do that, and this command is what's formed: $ sudo '/media/cdrom0/install' sudo: unable to execute /media/cdrom0/install: Permission denied What's the solution here?

• How do I send email with sendmail to external hosts?

  - by Jake

  If I wanted to send an email to a user on the same linux machine, I can run: echo -e "Subject: Foo\n\nBar\n" | sendmail -v jacob But if I run: echo -e "Subject: Foo\n\nBar\n" | sendmail -v [email protected] It will give me the error: 050 >>> MAIL From:<jacob@mu> SIZE=321 050 550 5.1.8 Cannot resolve your domain {mx-us011} If my machine has access to the internet but is behind a router and has no domain associated with it, can I use sendmail to send mail to this address? Do I need to connect through an SMTP server? Can I do that with sendmail? If I use sendmail's -f option and put my gmail account there it will work. Can (or should I) I use my IP address? echo -e "Subject: Foo\n\nBar\n" | sendmail -v -f [email protected] [email protected] I'm a bit lost on how all this comes together in sending mail from the command line.

• Printing to shared printers across VPN

  - by CYMR0

  I have a program that prints labels at five remote sites. Two sites, aren't working, but the rest are with an identical (as far as I can tell) setup. Using Wireshark, I have determined that the handshaking all goes well, but after the "Open Print File Response" the packet that is sent from the server, doesn't reach the client. But I'm a bit at a loss as to where I go from here. I know the port the packet was sent on (445) isn't being blocked, the RST packet gets sent on the same port and that gets there fine. It's also weird that the three out of five sites are working fine. This has been up and running for years without issue, all that we have changed is our connectivity (from DSL to bonded DSL). But this traffic is over a VPN - so it can't be the ISP interfering either can it? I'm totally stuck, and any help would be much appreciated. Thanks!

• Dealing with the customer / developer culture mismatch on an agile project

  - by Eric Smith

  One of the tenets of agile is ... Customer collaboration over contract negotiation ... another one is ... Individuals and interactions over processes and tools But the way I see it, at least when it comes to interaction with the customer, there is a fundamental problem: How the customer thinks is fundamentally different to how a software engineer thinks That may be a bit of a generalisation, yes. Arguably, there are business domains where this is not necessarily true---these are few and far between though. In many domains though, the typical customer is: Interested in daily operational concerns--short-range tactics ... not strategy; Only concerned with the immediate solution; Generally one-dimensional, non-abstract thinkers; Primarily interested in "getting the job done" as opposed to coming up with a lasting, quality solution. On the other hand, software engineers who practice agile are: Professionals who value quality; Individuals who understand the notion of "more haste less speed" i.e., spending a little more time to do things properly will save lots of time down the road; Generally, very experienced analytical thinkers. So very clearly, there is a natural culture discrepancy that tends to inhibit "customer collaboration". What's the best way to address this?

• Hidden files in Nautilus after extracting ISO

  - by Luis Alvarado

  I need to first point to the image below to explain a bit about what I find weird here: I extracted the informacion from an ISO I from Nautilus I could only see two folders but from the terminal I can see the rest of the files and folders. This folders do not have the . character in from of them to hide them from plain sight. When I try to "Show hidden files" in Nautilus, Nautilus closes itself. It does not show the hidden folders or files. Somehow they are hidden without using the normal dot in the beginning of the name. The have my user permission but no way of seeing them from Nautilus. I can interact with them but the fact that they appear hidden when I can see them inside the ISO and after extracting them they disappear is what confuses me. What permission or setting makes this folders appear hidden and does not let Nautilus show them and like I said before, trying to show them with the "Show hidden files" option crashes Nautilus and exits it. Forcing me to have to open Nautilus again from the Launcher.

• Internet Connectivity Issue

  - by MastaChief11

  Lately, I have been having issues connecting to the internet on one of my computers. The computer I am using now, however, is on the same network as the computer I am posting from. The issues seemed to randomly start about 2 days ago, and the only thing that seemed to fix the issue was to connect to Hotspot Shield VPN. I do not get any yellow warning signs by the Wi-Fi icon in the taskbar. I am sometimes able to use Google search, but I can never go to a website. I am also not able to re-install Hotspot Shield or update Flash because they have to connect to their company's servers. I have tried other VPN services just to see if it would fix anything, but as I expected, nothing changed. I am unsure of how I can fix the issue, and I appreciate all help given. I am running Windows 7 64 Bit Pro on a custom-built computer. Thanks.

• Chromium always starts as floating in awesome.wm

  - by xhochy

  I'm using awesome as window manager for a small surf&info terminal. Chromium is started directly after login on the first workspace and should be displayed fullscreen. I've set the layout of all workspaces to awful.layout.suit.max and followed Awesome FAQ so that Chromium and all other (automatically) started programs will be shown on the right workspace. All programs except Chromium will start correctly in fullscreen mode. I tried { rule = { class = "chromium-browser" }, properties = {floating = false, tag = tags[1][1]}} and { rule = { class = "chromium-browser" }, properties = {tag = tags[1][1]}} but Chromium will always start in floating mode. This is a bit annoying as you still see awesome's panel at the top.

• Teamviewer and Virtualbox issue: some keys don't work
