• Create a folder shortcut in "My Computer"

  - by Carlos Gil

  I'm trying to add shortcuts to folders in "My Computer". This .reg almost works, I can execute programs like EXPLORE.exe, but I want to open a folder in the same window. Can someone please point out how?

• How does the caller ID works on voip?

  - by Cawas

  Maybe this depends on the protocol, if so, I'm wondering mostly about SIP. That's all, just focus on the title please, but for a little background... I am using voipraider and I was just trying to set it up to have a caller id as my phone number, since I can't have this voip of mine on all the time (thus using DID or being able to receive calls through voip wouldn't be a solution here). I could actually make it work, but only using voipraider software. From other places, the caller ID doesn't show properly. So, I am wondering how it actually works to be able to go and look for a fix for this. I want details about the protocol, if that's relevant.

• Using a portable USB monitor in Ubuntu 13.04 (AOC e1649Fwu - DisplayLink)

  Having access to a little bit of IT hardware extravaganza isn't that easy here in Mauritius for exactly two reasons - either it is simply not available or it is expensive like nowhere. Well, by chance I came across an advert by a local hardware supplier and their offer of the week caught my attention - a portable USB monitor. Sounds cool, and the specs are okay as well. It's completely driven via USB 2.0, has a light weight, the dimensions would fit into my laptop bag and the resolution of 1366 x 768 pixels is okay for a second screen. Long story, short ending: I called them and only got to understand that they are out of stock - how convenient! Well, as usual I left some contact details and got the regular 'We call you back' answer. Surprisingly, I didn't receive a phone call as promised and after starting to complain via social media networks they finally came back to me with new units available - and *drum-roll* still the same price tag as promoted (and free delivery on top as one of their employees lives in Flic en Flac). Guess, it was a no-brainer to get at least one unit to fool around with. In worst case it might end up as image frame on the shelf or so... The usual suspects... Ubuntu first! Of course, the packing mentions only Windows or Mac OS as supported operating systems and without hesitation at all, I hooked up the device on my main machine running on Ubuntu 13.04. Result: Blackout... Hm, actually not the situation I was looking for but okay can't be too difficult to get this piece of hardware up and running. Following the output of syslogd (or dmesg if you prefer) the device has been recognised successfully but we got stuck in the initialisation phase.

A quick and dirty research on the net gave me some hints towards the udlfb framebuffer device for USB DisplayLink devices. By default this kernel module is blacklisted $ less /etc/modprobe.d/blacklist-framebuffer.conf | grep udl#blacklist udlblacklist udlfb and it is recommended to load it manually. So, unloading the whole udl stack and giving udlfb a shot: Oct 12 08:22:31 iospc2 kernel: [70126.642809] usbcore: registered new interface driver udlfb But still no reaction on the external display which supposedly should have been on and green. Display okay? Test run on Windows Just to be on the safe side and to exclude any hardware related defects or whatsoever - you never know what happened during delivery. I moved the display to a new position on the opposite side of my laptop, installed the display drivers first in Windows Vista (I know, I know...) as recommended in the manual, and then finally hooked it up on that machine. Tada! Display has been recognised correctly and I have a proper choice between cloning and extending my desktop. Testing whether the display is working properly - using Windows Vista Okay, good to know that there is nothing wrong on the hardware side just software... Back to Ubuntu - Kernel too old Some more research on Google and various hits recommend that the original displaylink driver has been merged into the recent kernel development and one should manually upgrade the kernel image (and both header) packages for Ubuntu. At least kernel 3.9 or higher would be necessary, and so I went out to this URL: http://kernel.ubuntu.com/~kernel-ppa/mainline/ and I downloaded all the good stuff from the v3.9-raring directory. The installation itself is easy going via dpkg: $ sudo dpkg -i linux-image-3.9.0-030900-generic_3.9.0-030900.201304291257_amd64.deb$ sudo dpkg -i linux-headers-3.9.0-030900_3.9.0-030900.201304291257_all.deb$ sudo dpkg -i linux-headers-3.9.0-030900-generic_3.9.0-030900.201304291257_amd64.deb As with any kernel upgrades it is necessary to restart the system in order to use the new one. Said and done: $ uname -r3.9.0-030900-generic And now connecting the external display gives me the following output in /var/log/syslog: Oct 12 17:51:36 iospc2 kernel: [ 2314.984293] usb 2-4: new high-speed USB device number 6 using ehci-pciOct 12 17:51:36 iospc2 kernel: [ 2315.096257] usb 2-4: device descriptor read/64, error -32Oct 12 17:51:36 iospc2 kernel: [ 2315.337105] usb 2-4: New USB device found, idVendor=17e9, idProduct=4107Oct 12 17:51:36 iospc2 kernel: [ 2315.337115] usb 2-4: New USB device strings: Mfr=1, Product=2, SerialNumber=3Oct 12 17:51:36 iospc2 kernel: [ 2315.337122] usb 2-4: Product: e1649FwuOct 12 17:51:36 iospc2 kernel: [ 2315.337127] usb 2-4: Manufacturer: DisplayLinkOct 12 17:51:36 iospc2 kernel: [ 2315.337132] usb 2-4: SerialNumber: FJBD7HA000778Oct 12 17:51:36 iospc2 kernel: [ 2315.338292] udlfb: DisplayLink e1649Fwu - serial #FJBD7HA000778Oct 12 17:51:36 iospc2 kernel: [ 2315.338299] udlfb: vid_17e9&pid_4107&rev_0129 driver's dlfb_data struct at ffff880117e59000Oct 12 17:51:36 iospc2 kernel: [ 2315.338303] udlfb: console enable=1Oct 12 17:51:36 iospc2 kernel: [ 2315.338306] udlfb: fb_defio enable=1Oct 12 17:51:36 iospc2 kernel: [ 2315.338309] udlfb: shadow enable=1Oct 12 17:51:36 iospc2 kernel: [ 2315.338468] udlfb: vendor descriptor length:17 data:17 5f 01 0015 05 00 01 03 00 04Oct 12 17:51:36 iospc2 kernel: [ 2315.338473] udlfb: DL chip limited to 1500000 pixel modesOct 12 17:51:36 iospc2 kernel: [ 2315.338565] udlfb: allocated 4 65024 byte urbsOct 12 17:51:36 iospc2 kernel: [ 2315.343592] hid-generic 0003:17E9:4107.0009: hiddev0,hidraw5: USB HID v1.10 Device [DisplayLink e1649Fwu] on usb-0000:00:1d.7-4/input1Oct 12 17:51:36 iospc2 mtp-probe: checking bus 2, device 6: "/sys/devices/pci0000:00/0000:00:1d.7/usb2/2-4"Oct 12 17:51:36 iospc2 mtp-probe: bus: 2, device: 6 was not an MTP deviceOct 12 17:51:36 iospc2 kernel: [ 2315.426583] udlfb: 1366x768 @ 59 Hz valid modeOct 12 17:51:36 iospc2 kernel: [ 2315.426589] udlfb: Reallocating framebuffer.

Let the system decide what's best for your hardware... $ xrandr --output DVI-0 --off$ xrandr --output DVI-0 --auto And there we go... Cloned output of main display: New kernel, new display... The external USB display works out-of-the-box with a Linux kernel > 3.9.0. Despite of a good number of resources it is absolutely not necessary to create a Device or Screen section in one of Xorg.conf files. This information belongs to the past and is not valid on kernel 3.9 or higher. Same hardware but Windows 8 Of course, I wanted to know how the latest incarnation from Redmond would handle the new hardware... Flawless! Most interesting aspect here: I did not use the driver installation medium on purpose. And I was right... not too long afterwards a dialog with the EULA of DisplayLink appeared on the main screen. And after confirmation of same it took some more seconds and the external USB monitor was ready to rumble. Well, and not only that one... but see for yourself. This time Windows 8 was the easiest solution after all. Resume I can highly recommend this type of hardware to anyone asking me. Although, it's dimensions are 15.6" it is actually lighter than my Samsung Galaxy Tab 10.1 and it still fits into my laptop bag without any issues. From now on... no more single screen while developing software on the road!

• Can I send some text to the STDIN of an active process running in a screen session?

  - by Richard Gaywood

  I have a long-running server process inside a screen session on my Linux server. It's a bit unstable (and sadly not my software so I can't fix that!), so I want to script a nightly restart of the process to help stability. The only way to make it do a graceful shutdown is to go to the screen process, switch to the window it's running in, and enter the string "stop" on its control console. Are there any smart redirection contortions I can do to make a cronjob send that stop command at a fixed time every day?

• Open source alternative for Canonical Landscape? [on hold]

  - by netvope

  From Canonical: Landscape is an easy-to-use systems management and monitoring service that enables you to manage multiple Ubuntu machines as easily as one through a simple Web-based interface. However, Landscape is not free. The RedHat counterpart Satellite has a free version called Spacewalk, but it doesn't work on Ubuntu. (There is an attempt to port Spacewalk to Debian, but it doesn't look like it's stable yet.) Are there any open source alternative to Landscape? Better yet, are there any Spacewalk-like software that works for both RedHat-based and Debian-based systems?

• Disable user_deny.db in Cyrus/imapd

  - by netmano

  We have a cyrus 2.4.12 on Debian, we use packages, rather than building each software ourselves. I am getting the this "log" constantly, a lot of, various users, and 8-10 times per user request: fetching user_deny.db entry for 'user123' I have searched for it, but haven't found a real solution, there were some patches for 2.3.xx, but we don't want ot build it, we prefer to use packages. Is there any solution to disable the user_deny.db at all. We don't need this feature. It wastes the CPU as disk.

• Spell check web pages using Firefox plugin

  - by Gopinath

  Having spelling mistakes on a website degrades customer experience by many times. Developers and website content creators spend good amount of time in going through the content manually to make sure that there are no spelling mistakes. At times few mistakes slip in as manual process is error prone. There are few web services and tool available in the market which provide automated spell checking services but they have certain limitations like – high fees to use the service, limitation on the number of pages they scan for errors, privacy issues, etc. What about a free tool that runs locally on your PC and spell checks unlimited web pages? Here comes Spell Checker extension for  Firefox web browser. This free Firefox extension is developed by  Gaurang, a Software Test Engineer based out in India. Once the extension is installed it adds a new context menu “Check Spelling” and a small icon to Add-On bar. To check spellings of a web page just click on the icon or the context menu and it will highlight all the errors on the page. By default SpellChecker extension uses US English dictionary to find spell mistakes and supports spell checking in other languages with installation of dictionaries.

• How can I monitor network traffic in an all Mac home network?

  - by raiglstorfer

  I have an all Mac network consisting of an Airport Extreme, 1 MacPro, 1 Mac Mini, 2 MackBook Pros, 2 iPads, and 2 iPhones. The Mac Pro is connected directly to the Airport Extreme via Cat5 and the rest is all running via Wireless. Lately I've been getting prompted by Google to enter Capchas frequently. The message states that I might have software running on my network I'm not aware of. My wireless router is password protected using WPA2 Personal and I frequently change my password so I don't think someone is using the network from outside (but I've no way to confirm this). I'm looking for a relatively cheap (preferably open source) solution that would enable me to monitor and profile the network usage by machine and port. Can someone recommend a solution?

• 32-bit and 64-bit CPU/OS [closed]

  - by learnerforever

  Possible Duplicates: how to know if a computer is 32 bit or 64 bit 32-bit v/s 64-bit systems Hi, This 32-bit and 64-bit thing baffles me. It's not often that I run across it, but when I do, it baffles me. Like when I want to download software from http://www.google.com/ime/transliteration/ it asks me which version to download. I have win XP running on my thinkpad machine. How do I find out if my hardware is 32-bit or 64-bit. Also, how do I find if OS is 32-bit or 64-bit and thus how to know which version to download from this link. Also for any installed application say firefox, how do I know which bit version is installed. How popular are 64-bit hardware/OSs?. Are all the new CPUs and OSs supporting 64-bit and 32-bit for backwards compatible or 64-bit is still a luxury? Thanks,

• Alternatives to Professional Version Control

  - by greengit

  We're teaming up with some non programmers (writers) who need to contribute to one of our projects. Now they just don't like the idea of using Git (or anything for that matter) for version controlling their work. I think this is because they just don't find it worthwhile to wrap their heads around the twisted concepts of version control. (when I first introduced them to branching and merging -- they looked like I was offending them.) Now, we're not in a position to educate them or convince them to use it. We're just trying to find alternatives so that we get all their work versioned (which is what we need) -- and they get easy workflow and concentrate on what they do. I have come up with some ideas... tell them to save their work as a separate file every time they make some non-trivial change, and then use a diff on our side to just track changes. write a program (in Python) that implements the "milestones" in CSSEdit in some way. About the project: It is a natural language processing system (written in C + Python). We've hired some writers to prepare inputs for the system in different languages. And as we evolve the software, we'd need those writers to make changes to their inputs (articles). Sometimes the changes are very small (a word or two), and other times big. The reason we need to version control those changes is because every small/big change in the input has the potential to change the system's output dramatically.

My user has admin rights, and i can execute admin functions from the GUI (such as System Prefs, updating software etc). However, within Terminal, sudo has stopped accepting the password. I have repaired permissions and restarted. Some pointers ask me to use Directory Utility, but in this version it does not have a "set root user" option. I downloaded ServerAdminTool 10.5.7 but this does not work on my system. Some say to add myself to "wheel" group, but i need sudo for that. Some say if i am in admin group, i should be able to sudo, but this is not happening. (Using OS X Snow Leopard 10.6.6, earlier 10.5.8) MODERATOR: please delete this question. The issue had to do with Textpander expanding the password resulting in sudo failing. Not an OS upgrade issue.

• Researching runtime technologies (Xmas fun with HTML5)

  - by Eric Nelson

  The Internet Explorer 9.0 team just posted about Pirates love Daises. This is a showcase game for the power of HTML 5 running inside IE 9.0 – and the author has done a fantastic job (you can get more details from Grant’s blog post). A game developer is an ISV (Independent Software Vendor) – a B2C  ISV. In my role I don’t (typically) work with B2C ISVs, hence a reasonable question is “Why blog about it?”. I think applications like this demonstrate the power of HTML 5 and IE9 for delivering really rich user experiences which have the promise of working cross browser and cross platform - in the future as HTML5 capable browsers become the norm. Microsoft is investing heavily in implementing a great “run time” in IE9 if cross platform is an important requirement for your UX. And the other reason for blogging this… it is nearly Xmas and we all should be having a little more fun on the run in. Hence you can play with confidence that your defence to your manager is “I’m just researching a powerful runtime that Microsoft is working on which could be significant to our future B2B product directions” Play now (Needs HTML 5 browser such as IE9) Related Links: To install IE9 Beta or the Preview (which won’t replace your existing IE) check our the IE9 TestDrive center. Learn about our other important UX runtime with the on-demand recordings of the Silverlight FireStarter event.

• JRockit R28 "Ropsten" released

  - by tomas.nilsson

  R28 is a major release (as indicated by the careless omissions of "minor" and "revision" numbers. The formal name would be R28.0.0). Our customers expect grand new features and innovation from major releases, and "Ropsten" will not disappoint. One of the biggest challenges for IT systems is after the fact diagnostics. That is - Once something has gone wrong, the act of trying to figure out why it went wrong. Monitoring a system and keeping track of system health once it is running is considered a hard problem (one that we to some extent help our customers solve already with JRockit Mission Control), but doing it after something occurred is close to impossible. The most common solution is to set up heavy logging (and sacrificing system performance to do the logging) and hope that the problem occurs again. No one really thinks that this is a good solution, but it's the best there is. Until now. Inspired by the "Black box" in airplanes, JRockit R28 introduces the Flight Recorder. Flight Recorder can be seen as an extremely detailed log, but one that is always on and that comes without a cost to system performance. With JRockit Flight Recorder the customer will be able to get diagnostics information about what happened _before_ a problem occurred, instead of trying to guess by looking at the fallout. Keywords that are important to the customer are: • Extremely detailed, always on, diagnostics information • No performance overhead • Powerful tooling to visualize the data recorded. • Enables diagnostics of bugs and SLA breaches after the fact. For followers of JRockit, other additions are: • New JMX agent that allows JRMC to be used through firewalls more easily • Option to generate HPROF dumps, compatible with tools like Eclipse MAT • Up to 64 BG compressed references (previously 4) • View memory allocation on a thread level (as an Mbean and in Mission Control) • Native memory tracking (Command line and Mbean) • More robust optimizer. • Dropping support for Java 1.4.2 and Itanium If you have any further questions, please email [email protected]. The release can be downloaded from http://www.oracle.com/technology/software/products/jrockit/index.html

• Use Modern Apps in Windows 7

  - by soandos

  It seems like a basic question, but is there a way to run windows 8 (Modern Apps) in windows 7 (without a VM, that seems like cheating)? My hunch is that it would be possible with some sort of hack, as the code is written in the same .Net languages as many other programs. The only issue would be intercepting the finger to corner gestures, but I am not sure how much is there really (is it just a location, or a special win API call). Is there software that can do this, or options that need to be changed to make this work?

• High-Level Application Architecture Question

  - by Jesse Bunch

  So I'm really wanting to improve how I architect the software I code. I want to focus on maintainability and clean code. As you might guess, I've been reading a lot of resources on this topic and all it's doing is making it harder for me to settle on an architecture because I can never tell if my design is the one that the more experienced programmer would've chosen. So I have these requirements: I should connect to one vendor and download form submissions from their API. We'll call them the CompanyA. I should then map those submissions to a schema fit for submitting to another vendor for integration with the email service provider. We'll call them the CompanyB. I should then submit those responses to the ESP (CompanyB) and then instruct the ESP to send that submitter an email. So basically, I'm copying data from one web service to another and then performing an action at the latter web service. I've identified a couple high-level services: The service that downloads data from CompanyA. I called this the CompanyAIntegrator. The service that submits the data to CompanyB. I called this CompanyBIntegrator. So my questions are these: Is this a good design? I've tried to separate the concerns and am planning to use the facade pattern to make the integrators interchangeable if the vendors change in the future. Are my naming conventions accurate and meaningful to you (who knows nothing specific of the project)? Now that I have these services, where should I do the work of taking output from the CompanyAIntegrator and getting it in the format for input to the CompanyBIntegrator? Is this OK to be done in main()? Do you have any general pointers on how you'd code something like this? I imagine this scenario is common to us engineers---especially those working in agencies. Thanks for any help you can give. Learning how to architect well is really mind-cluttering.

• Scaling Scrum within a group of 100s of programmers

  - by blunders

  Most Scrum teams lean toward 7-15 people **, though it's not clear how to scale Scrum among 100s of people, or how the effectiveness of a given team might be compared to another team within the group; meaning beyond just breaking the group into Scrum teams of 7-15 people, it's unclear how efforts between the teams are managed, compared, etc. Any suggestions related to either of these topics, or additional related topics that might be of more importance to account for in planning a large scale SCRUM grouping? ** In reviewing research related to the suggested size of software development teams, which appears to be the basis for the suggested Scrum team size, I found what appears to be an error in the research which oddly appears to show that bigger teams (15+ ppl), not smaller teams (7 ppl) are better. UPDATE, "Re: Scrum doesn't scale": Made huge amounts of progress on personally researching the topic, but thought I'd respond to the general belief of some that Scrum doesn't scale by citing a quote from Succeeding with Agile by Mike Cohn : Scrum Does Scale: You have to admire the intellectual honesty of the earliest agile authors. They were all very careful to say that agile methodolgies like Scrum were for small projects. This conservatism wasn’t because agile or Scrum turned out to be unsuited for large projects but because they hadn’t used these processes on large projects and so were reluctant to advise their readers to do so. But, in the years since the Agile Manifesto and the books that came shortly before and after it, we have learned that the principles and practices of agile development can be scaled up and applied on large projects, albeit it with a considerable amount of overhead. Fortunately, if large organizations use the techniques described regarding the role of the product owner, working with a shared product backlog, being mindful of dependencies, coordinating work among teams, and cultivating communities of practice, they can successfully scale a Scrum project.

• Good default for XDG_RUNTIME_DIR?

  - by cadrian

  The XDG Base Directory Specification is a very interesting spec for user directories. It also provides good default values, except for XDG_RUNTIME_DIR. Now I am writing a software that needs to create named pipes. It is a per-user client-server framework (there is a FIFO for the server and a FIFO per client). If XDG_RUNTIME_DIR is not defined, I am currently using a per-user subdirectory in /tmp — but it does not ensure all the specified conditions (viz. the paragraph starting with "The lifetime of the directory MUST be bound to the user being logged in…") Is /tmp/myserver-$USER good enough? Edit I saw elsewhere a few suggestions: . is quite unsatisfactory (at least because it is not an absolute path). I also saw /var/run/user/$USER — not bad, but that directory does not exist (at least on my box running a Debian testing)

• Configuring Server with no monitor

  - by Scandalist

  Sitting in front of me is an HP DL 380 Generation 4 with no monitor. I'd like to install an OS on the thing but for reasons obvious, I can't. I got excited when I found the ILO port on the back but unless you have a subscription it has limited functionality. I was thinking maybe there was some software out there that booted into some kind of remote access server? When I tested it with a monitor (A friends) I set the BIOS to boot from USB so anything I can load onto a stick should boot. Ideas? Hacks?

• Using JuJu with private Openstack cloud deployment?

  - by user76054

  I'm seeing a number of problems trying to use JuJu with our internally deployed Openstack cloud. Most of this appears to be centered around DNS host resolution as well as the need to deal with our company's internal HTTP proxies. Our Openstack deployment relies upon an unroutable 172.16.0.0/12 block of addresses for VLAN allocation to each project (tenant) hosted on our internal cloud. User's have the option of assigning one or more floating addresses to instances, allocated from a block of routable addresses on our internal companies LAN. Currently, Openstack doesn't register instance names with anything other than the DNSMASQ service running on the cloud controller. As such, there's no way to resolve this address through our internal DNS hierarchy (this issue has already been reported as Bug #945505). As such, even though I can bootstrap my JuJu server node, I can't connect to it with the JuJu client, since it can't resolve the local (private) network name. I am able to ssh to the node, once I've assigned it an internally routable (i.e. floating) address. Which leads to the next issue. Next, to install software on an instance running in our cloud, it must have our internal proxy address defined - either in the apt.conf file or via environment variables. Unfortunately, when bootstrapping the server node, there's no provision to pass this info into a instance via JuJu environment.yaml file (if this is even the best way to handle this issue). As a result, the bootstrap node is unable to install the required packages. I'm assuming (dangerous, I know) that the way that I've deployed Openstack in our internal environment is probably not unique. Has anyone else encountered these issues? And more importantly, are work arounds available? Regards, Ross

• Monitor HTTP usage on network from Linux free

  - by David

  I manage a small office network. I am looking to start monitoring/logging internet usage (website requests) for each user on a small network. All the windows clients are running through a switch to a BT router. I also have a linux (centos) machine which is connected as a client to the BT router as well. Is there any free software I can install on the linux box (or my own machine) to allow me to log and monitor websites requested by users kind of like browser history. Ideally, something that would collect each client's browser history in 1 place. Thanks

• Extreme Optimization Numerical Libraries for .NET – Part 1 of n

  - by JoshReuben

  While many of my colleagues are fascinated in constructing the ultimate ViewModel or ServiceBus, I feel that this kind of plumbing code is re-invented far too many times – at some point in the near future, it will be out of the box standard infra. How many times have you been to a customer site and built a different variation of the same kind of code frameworks? How many times can you abstract Prism or reliable and discoverable WCF communication? As the bar is raised for whats bundled with the framework and more tasks become declarative, automated and configurable, Information Systems will expose a higher level of abstraction, forcing software engineers to focus on more advanced computer science and algorithmic tasks. I've spent the better half of the past decade building skills in .NET and expanding my mathematical horizons by working through the Schaums guides. In this series I am going to examine how these skillsets come together in the implementation provided by ExtremeOptimization. Download the trial version here: http://www.extremeoptimization.com/downloads.aspx Overview The library implements a set of algorithms for: linear algebra, complex numbers, numerical integration and differentiation, solving equations, optimization, random numbers, regression, ANOVA, statistical distributions, hypothesis tests.
