• Which software could I use to setup a 4in6 IP tunnel (RFC 2473) on GNU/Linux

  - by Mildred

  Here is my problem. I have a server A that has two IP addresses. One public IPv4 and one IPv6. Server B has only one IPv6 address. I want to host most of my services on server B (because I have more disk space on it, I can control it better) but I need the IPv4 of the server A. I would like to set up a 4in6 tunnel (RFC 2473) between A and B so that I can transfer the traffic from the IPv4 address in A to B. If needed, I can request another IPv4 address on the server A, but I'd prefer not to. My question is: which software use to do the 4in6 tunnelling? I suppose OpenVPN can do the thing, but is there any implementation of the 4in6 protocol on Linux? A little more challenging: the IPv4 address comes from a venet interface, which cannot be bridged. How could I transfer ownership of this address I don't use on server A to the server B? Thank you

• Integrating different branches from external sources into a single Mercurial repository

  - by dukeofgaming

  I'm currently working in a company using Perforce and am making way for distributed version control with Mercurial. I've had success importing Perforce history using the perfarce (quite a suitable name, I laugh every time I see/say it) however, this only works with a single branch at a time. Here's how my P4 integration setup works: In perforce, create a "client", which is kind of a description of what you will be constantly updating/checking-out. This can only address one branch at a time (trunk or other). Once you do this, run hg clone p4://<server>/<client_name> Go to .hg/hgrc and put the perforce path line: perforce = p4://<server>/<client_name> Work normally with the code under mercurial, do hg pull perforce to sync up, hg push to export a changelist What I'd like to be able to do is have a perforce path per branch and have everything work in the same repository. Now, pushing is not a problem, however, if I pull the history from another branch it would end up at the default branch. I'd like to be able to do something like hg pull perforce-R5 and have it land in mercurial's R5 branch. Even if I have no merging history, it would be sweet enough to be able to preserve it. There are also other plugins for CVCSs that let you integrate mercurial, but AFAIK the subversion one has the same problem. I don't think there is a straight-through way of doing this, but as long as I could automate the process with some hooks and scripts in a single Mercurial machine, that would be good enough.

• The Social Business Thought Leaders - Steve Denning

  - by kellsey.ruppel

  How is the average organization doing? Not very well according to a number of recent books and reports. A few indicators provide quite a gloomy picture: Return on assets and invested capitals dropped to 25% of its value in 1965 in the entire US market (see The Shift Index by John Hagel) Firms are dying faster and faster with the average lifespan of companies listed in the S&P 500 index gone from 67 years in the 1920s to 15 years today (see Creative Disruption by Richard Foster) Employee engagement ratio, a high level indicator of an organization’s health proved to affect performance outcomes, does not exceed on average 20%-30% (see Employee Engagement, Gallup or The Engagement Gap, Towers Perrin) In one of the most enjoyable keynotes of the Social Business Forum 2012, Steve Denning (Author of Radical Management and Independent Management Consultant) explained why this is happening and especially what leaders should do to reverse the worrying trends. In this Social Business Thought Leaders series, we asked Steve to collapse some key suggestions in a 2 minutes video that we strongly recommend. Steve discusses traditional management - that set of principles and practices born in the early 20th century and largely inspired by thinkers such as Frederick Taylor and Henry Ford - as the main responsible for the declining performance of modern organizations. While so many things have changed in the last 100 or so years, most companies are in fact still primarily focused on maximizing profits and efficiency, cutting costs, coordinating individuals top-down through command and control. The issue is, in a knowledge intensive, customer centred, turbulent market like the one we are experiencing, similar concepts are not just alienating employees' passion but also destroying the last source of competitive differentiation left: creativity and the innovative potential. According to Steve Denning, in a phase change from old industrial to a creative, collaborative, knowledge economy, the answer is hidden in a whole new business ecosystem that puts the individual (both the employee and the customer) at the center of the organization. He calls this new paradigm Radical Management and in the video interview he articulates the huge challenges and amazing rewards our enterprises are facing during this inevitable transition.

• Replicate Oracle to MySQL

  - by Rosdi

  I am developing a web apps, this web application will be using MySQL. Now I need to replicate my client's Oracle database into MySQL, only a few tables will be involved.. a table can be up to 2-3 million rows. I only have SELECT privilege on this Oracle, so don't ask me to install any kind of service on the Oracle machine. I have complete control on the MySQL side however. The replication is only one way (Oracle to MySQL). I can write a simple script to truncate MySQL table and repopulate it every night but I think this is very inefficient, there must be a better way. Is there any free tools I can use? Expensive database replication system is definitely out of the question.

• What causes bad performance in consumer apps?

  - by Crashworks

  My Comcast DVR takes at least three seconds to respond to every remote control keypress, making the simple task of watching television into a frustrating button-mashing experience. My iPhone takes at least fifteen seconds to display text messages and crashes ¼ of the times I try to bring up the iPad app; simply receiving and reading an email often takes well over a minute. Even the navcom in my car has mushy and unresponsive controls, often swallowing successive inputs if I make them less than a few seconds apart. These are all fixed-hardware end-consumer appliances for which usability should be paramount, and yet they all fail at basic responsiveness and latency. Their software is just too slow. What's behind this? Is it a technical problem, or a social one? Who or what is responsible? Is it because these were all written in managed, garbage-collected languages rather than native code? Is it the individual programmers who wrote the software for these devices? In all of these cases the app developers knew exactly what hardware platform they were targeting and what its capabilities were; did they not take it into account? Is it the guy who goes around repeating "optimization is the root of all evil," did he lead them astray? Was it a mentality of "oh it's just an additional 100ms" each time until all those milliseconds add up to minutes? Is it my fault, for having bought these products in the first place? This is a subjective question, with no single answer, but I'm often frustrated to see so many answers here saying "oh, don't worry about code speed, performance doesn't matter" when clearly at some point it does matter for the end-user who gets stuck with a slow, unresponsive, awful experience. So, at what point did things go wrong for these products? What can we as programmers do to avoid inflicting this pain on our own customers?

• How to PERMANENTLY disable touchpad tap-to-click on Dell Inspiron/Windows 7

  - by Graham

  Hi all - my first time here, so I hope you can help. I've seen a lot of stuff on various forums (including here) about disabling the annoying "tap" function on a laptop touchpad. I learned the hard way not to de-install the driver (as the software suggests), since you then loose the Synaptic tab in the mouse control settings, and with it all means to modify the touchpad settings ... indicentally, if this happens to you, reboot in safe mode and do a restore, and the synaptic tab comes back. Not ideal, I know, but it works. Anyway, I have the most up-to-date drivers, and I can go to the Synaptics tab and can disable the tap-to-click function no problem. However, next time the machine is booted, tap-to-click is back on. It can alsways be disabled, but it's pain having to reset it every time the mchine is powered up. Is there a way to permanently disable it, once and for all? Thanks in advance, Graham

• Firefox 3.5.6 Uninstaller not working

  - by Wesley

  Hi all, I want to uninstall Firefox 3.5.6 in favor of Opera 10.10. However, I've went into Control Panel Add or Remove Programs and tried clicking Remove from there, but nothing happens. I go into the Program Files for FIrefox and find the Uninstaller folder and click the helper.exe found in there. Still, nothing happens. Is there some possible way to uninstall Firefox without screwing up the rest of my computer?

• Munq is for web, Unity is for Enterprise

  - by oazabir

  The Unity Application Block (Unity) is a lightweight extensible dependency injection container with support for constructor, property, and method call injection. It’s a great library for facilitating Inversion of Control and the recent version supports AOP as well. However, when it comes to performance, it’s CPU hungry. In fact it’s so CPU hungry that it makes it impossible to make it work at Internet Scale. I was investigating some CPU issue on a portal that gets around 3MM hits per day and I found unusually high CPU. Here’s why: I did some CPU profiling on my open source project Dropthings and found that the highest CPU is consumed by Unity’s Resolve<>(). There’s no funky use of Unity in the project. Straightforward Register<>() and Resolve<>(). But as you can see, Resolve<>() is consuming significantly high CPU even after the site is warm and has been running for a while. Then I tried Munq, which is a basic Dependency Injection Container. It has everything you will usually need in a regular project. It boasts to be the fastest DI out there. So, I converted all Unity code to Munq in Dropthings and did a CPU profile and Whala!   There’s no trace of any Munq calls anywhere. That proves Munq is a lot faster than Unity.

• The Future of Life Assurance Conference Recap

  - by [email protected]

  I recently wrote about the Life Insurance Conference held in Washington, DC last month. This week I was both an attendee and guest speaker the 13th Annual Future of Life Assurance Conference held at The Guoman Tower in London, UK. It's amazing that these two conferences were held on opposition sides of the Atlantic Ocean and addressed many of the same session topics and themes. Insurance is certainly a global industry! This year's conference was attended by many of the leading carriers and CEOs in the UK and across Europe.The sessions included a strong lineup of keynote speakers and panel discussions from carriers such as Legal & General, Skandia, Aviva, Standard Life, Friends Provident, LV=, Zurich UK, Barclays and Scottish Life. Sessions topics addressed a variety of business and regulatory issues including: Ensuring a profitable future Key priorities in regulation The future of advice The impact of the RDR on distribution Bancassurance Gaining control of the customer relationship Revitalizing product offerings In addition, Oracle speakers (Glenn Lottering and myself) led specific sessions on gearing up for Solvency II and speeding product development through adaptive rules-based systems. The main themes that played throughout many of the sessions included: change is here, focusing on customers, the current economic crisis has been challenging and the industry needs to get back to the basics and simplify - simplify - simplify. Additionally, it is clear that the UK Life & Pension markets will be going through some major changes as new RDR regulation related to advisor fees and commission and automatic enrollment are rolled out in 2012 Roger A.Soppe, CLU, LUTCF, is the Senior Director of Insurance Strategy, Oracle Insurance.

• Mouse-usable alt-tab for windows 7

  - by Florian Peschka

  I'm using Windows 7 with ye good olde Windows 2000 style (I favor usability and space over fancy-pants aero and effects) and am looking for a way I can make the ALT-TAB-Control interactable with my mouse. I generally have many many windows open, and pressing tab or shift-tab over and over again begings to really frustrate me, if i want to reach a certain program. Of course, I could just select the program on my taskbar, but that takes even longer. I really like the way mac os x has its alt-tab menu - more or less exactly the same, but I can select the program with my mouse. Is there something like that for my environment?

• Web based console connections not working in Windows 7 posted: Jan 20, 2010 8:55 AM

  - by nmeth

  For slightly complicated reasons we tend to give people console access to VMs via the webui. This has worked fine in the past, however when the users update their client machines to Windows 7 (or Vista, I am told, although I have not tested that), then the console fails to work. On IE8, having allowed the ActiveX control, the tab causes a "Internet Explorer has stopped working" dialog. On Firefox 3.5 , once the plugin has been installed, using the console causes the browser to crash. I've updated to the most recent VC 2.5 release, and ESX 3.5u5. Anyone else seeing this? Any clues how to get round it (other than using the fat client). Nigel.

• Mini-ITX board for AM3 Athlon X4 600e processor.

  - by Kamil Zadora

  Hello, I am planning to build a PC to control a robotic platform that I am building (about 50% complete). I need more power than ATOM platform could bring, as the robot will need to do on the fly image processing to work as intended. I was considering using Athlon X4 600e as it is rated 45W Maximum output. Probably underclocked it would go lower than 30-35W. I do not I'am at very long battery life, but the 17Ah, 12V battery should keep it running for few hours. My problem is: motherboard. I am space limited so I am looking for a nice mini-itx AM3 motherboard to match the processor. It is hard to find many tests about power usage of the motherboards itself (for example, when using the same processor on different motherboards, test are usualy done in the opposite matter). Could you provide any motherboard examples or suggest what chipset to look for? Thank you in advance.

• How to dismiss the Windows 8.1 Upgrade banner?

  - by user81430

  As of today, my Windows 8 system is displaying a large banner covering about a quarter of the screen, demanding that I upgrade to Windows 8.1 for free. The banner helpfully informs me that that I can continue to use the computer while the upgrade is downloading. There's a button to go to the store for the upgrade, but no other choices, such as No Thanks, Maybe Later, or Absolutely Not. I can't find a way to dismiss the banner, and I can start programs but can't give them focus while the banner is present. So I'm dead in the water. How can I fix this? Bringing up Task Manager doesn't give me any options. My employer doesn't yet support Windows 8.1 (which is also an issue, but beyond my control) so I won't be able to connect to work if install the upgrade. So there is no way on God's green earth that I'm going to install this upgrade now.

• How do I make an exe into a service on Windows?

  - by user3677994

  I recently made an application that has multiple parts. One of the parts is a networking tool - it always starts with the OS, and it never displays any sort of message. It does, however, start an incredibly irritating console, which is impossible to get rid of without closing the program itself (please just accept this one as given). I have decided to work around this problem by starting the program (it's a *.exe) as a service, thus stopping it from showing up at all. As the application will be distributed to various computers (hence the need for a networking tool in the first place). I need a way to make this program install as a service (so, I don't really want answers that tell me to go through a series of menus on the Control Panel or download a 3rd-party application that has to stay on whichever computer the service will run on). How can I do this?

• Reclaim Vertical UI Space by Moving Your Tabs to the Side in Firefox

  - by Asian Angel

  Are you looking for a way to move your tabs to the side in Firefox and gain access to more vertical UI space? The Vertical Tabs extension for Firefox lets you accomplish both in a matter of moments. As soon as you install the extension and restart Firefox the Tab Bar will be automatically converted into a shiny new Vertical Tabs Sidebar. All that you have to do is start enjoying the extra vertical UI space. Some things to keep in mind when using the extension are: You can easily adjust the width of the sidebar to suit your needs using the mouse (very nice!) The Firefox Menu Button, Panorama Button, and Tab Control controls move to the bottom of the sidebar (see screenshot above) You can group tabs if needed or desired There is no option available to move the sidebar to the right side of the browser at the moment The use of Personas themes (or other themes) may affect how the text for the tabs will look (i.e. a slightly fuzzy shadow effect when not selected as seen in the screenshot above) Note: Works with Firefox 4.0b7 – 4.0.* Install the Vertical Tabs Extension [Mozilla Add-ons] Latest Features How-To Geek ETC Should You Delete Windows 7 Service Pack Backup Files to Save Space?

• What's the difference between General Ledger Transfer Program, Create Accounting and Submit Accounting?

  - by Oracle_EBS

  In Release 12, the General Ledger Transfer Program is no longer used. Use Create Accounting or Submit Accounting instead. Submit Accounting spawns the Revenue Recognition Process. The Create Accounting program does not.

• Two virtual computers using one laptop?

  - by JP19

  Hi, I have a laptop and an external display. I am able to use the external display either as extended desktop OR duplicate desktop. I also use a separate keyboard and mouse. So effectively, the laptop acts just as a box without display. I want to know is it possible to use the laptop as 2 virtual PCs. (with separate control). I.E., one person uses the laptop as a laptop, and other person can simultaneously connect a keyboard and mouse and the external display and effectively get a second PC. OS I am using - windows (thought solution for other OSes are welcome). Laptop is a Dell Precision M6300. thanks JP

• Migrating a Windows Server to Ubuntu Server to provide Samba, AFP and Roaming Profiles

  - by Dan

  I'm replacing our old Windows XP Pro office server with a HP Microserver running Ubuntu Server 12.04 LTS. I'm not a Linux expert but I can find my way around a terminal prompt, I'm a Mac user by choice. The office use a mix of Windows XP Pro machines and OSX Lion laptops. I included Samba during installation, and I'm planning on using Netatalk for the AFP and Bonjour sharing. I'd quite like to have samba make the server appear in 'My network places' on the Windows machines the way Bonjour makes it appear in finder on the Macs, if this is possible? I want to get to a point so that a user logging into Windows, gets connected to the Ubuntu server (do they need an Ubuntu user account?) which get them their shares and their Windows user profile (though a standard profile across users would do). The upshot is to make centralised control of user accounts (e.g. If a person leaves, killing their account on the server stops their Windows logon and ability to access Samba shares) and to ensure files aren't stored on the individual machines for backup/security purposes. I want to make this as simple as possible, so don't want to have loads of stuff I don't need, I just can't figure out: What I need at the server end: - will Samba be enough (already installed as part of initial installation), or will I need to cock around with LDAP (and how does this interact with Samba) - For someone of moderate Linux competence like me, is there a package that offers easy admin of user accounts, e.g. a GUI like phpLDAPadmin (if LDAP is necessary) How to configure the XP machines: - do I need to have the XP machines set up as a domain controller (I've no idea, really) - roaming profiles looks to offer the feature of putting the user's files on the server rather than the machine itself along with a profile that follows the user from machine to machine. Syncing Mac user's home folders with the server This is less of a concern because I can set up Time Machine if it comes to it, but I'd appreciate any recommendations of what approach I should take having the Mac home folders synced to the server.

• Syslog/kernlog filling up with "did not claim interface N before use"

  - by Wayne Werner

  As I discovered when asking this question, it appears that demond_nscan is trying to use a device without claiming it. And it does it.... hundreds of time per second apparently. This makes kern.log and syslog huge (100GB ). In this particular case the problem is directly a result of some Lexmark drivers that were installed (found at /usr/local/lexmark/unix_scan_drivers/bin/demond_nscan). Here are a few things I know: The drivers are for an all-in-one printer/scanner device. There was a previous lexmark printer-only that was installed with CUPS This driver was the one for CUPS systems, and I think that it automatically added it to the list of printers in CUPS. The issue started spamming kern/syslog only after these drivers were installed, using the lexmark installers While googling around I found this thread that's not completely related, but it does mention that it might be happening when two drivers try to control the same device at the same time. How can I resolve this issue so that either I only have one driver, or get the driver to claim the device before usage?

• kernel software trap handling

  - by Tony

  I'm reading a book on Windows Internals and there's something I don't understand: "The kernel handles software interrupts either as part of hardware interrupt handling or synchronously when a thread invokes kernel functions related to the software interrupt." So does this mean that software interrupts or exceptions will only be handled under these conditions: a. When the kernel is executing a function from said thread related to the software exception(trap) b. when it is already handling a hardware trap Is my understanding of this correct? The next bit: "In most cases, the kernel installs front-end trap handling functions that perform general trap handling tasks before and after transferring control to other functions that field the trap." I don't quite understand what it means by 'front-end trap handling functions' and 'field the trap'? Can anyone help me?

• SQL Server for the Oracle DBA Links

  - by BuckWoody

  I do a presentation (and a class) called "SQL Server for the Oracle DBA". It's a non-marketing overview that gives you the basics of working with SQL Server if you're already familiar wtih how Oracle works. This class and these links DO NOT help you with "Why should I use Oracle/SQL Server instead of Oracle/SQL Server" - I'll assume you're already there, and if not, there are LOTS of sites to help you make that decision. Although these links might contain slight marketing slants (I don't control them) I've tried to get the best links I can. Feel free to comment here to add more/better links. As such, these aren't links that help you work with Oracle - they are links to help you work with SQL Server. Some of them contain more information than you actually need, others don't have near enough. Taken together (and with the class) you're able to get done what you need to do.
