• Intel Centrino Wireless N 1000 doesn't work on a Lenovo Z560

  - by Timetraveler

  I upgraded my Ubuntu 11.04 to 11.10 and my Wifi has stopped working. I have a Lenovo Z560 that has Intel centrino wireless-N 1000. I have searched various threads having similar problems for a solution and have no success. The wlan0 is not even showing up in rfkill. Please help me find a solution. I am giving below the output of various debug commands. Thanks in advance.

• How can I fix broken i915 drivers for Intel GPUs?

  - by Alen Mujezinovic

  I've got troubles getting the i915 drivers to work correctly on my laptop (HP Pavilion DM4 2101ea). Specifically, the laptop screen goes black and stays black after the splash graphic when booting both from USB key and from harddrive. To get anything on to the display after the splash screen I have to boot either with acpi=off nomodeset i915.modeset=0 I'd rather not turn ACPI off because I like my fans spinning and nomodeset is a bit overkill, so for now I'm booting with i915.modeset=0. Unfortunately, this turns off KMS and my current maximum resolution on the laptop screen is fixed to 1024x768 instead of its real capability. When not setting any of the above boot flags and I plug in an external monitor, the external monitor works fine. When booting with the flags, the external monitor works fine too, but can only do 1024x768 and can't do anything else than mirroring the laptop display. I did upgrade the i915 drivers from 2.17 that ship with Precise to 2.19 which are the most recent ones but without luck of getting anything to display. Here's my lspci output: 00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09) 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 00:16.0 Communication controller: Intel Corporation 6 Series/C200 Series Chipset Family MEI Controller #1 (rev 04) 00:1a.0 USB controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #2 (rev 05) 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05) 00:1c.0 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 1 (rev b5) 00:1c.2 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 3 (rev b5) 00:1c.4 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 5 (rev b5) 00:1d.0 USB controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #1 (rev 05) 00:1f.0 ISA bridge: Intel Corporation HM65 Express Chipset Family LPC Controller (rev 05) 00:1f.2 SATA controller: Intel Corporation 6 Series/C200 Series Chipset Family 6 port SATA AHCI Controller (rev 05) 00:1f.3 SMBus: Intel Corporation 6 Series/C200 Series Chipset Family SMBus Controller (rev 05) 01:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01) 02:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd.

I've never had problems with Intel hardware on Ubuntu before so this is very surprising. If you could provide a method to make i915 work, suggest alternative drivers a way to boot with i915.modeset=0 but higher resolutions and KMS on or explain what is happening and how to fix it I'll give you an answer badge. :) Thanks

• Outlying DBAs

  - by steveh99999

  Read an interesting book recently, ‘Outliers – the story of success’ by Malcolm Gladwell. There’s a good synopsis of the book here on wikipedia. I don’t want to write in detailed review of the book, but it’s well worth a read. There were a couple of sections which I thought were possibly relevant to IT professionals and DBAs in particular. Firstly, ‘the 10,000 hour rule’, in this section Gladwell asserts that to be a real ‘elite performer’ takes 10,000 hours of practice. ‘Practice isn’t the thing you do once you’re good, it’s the thing you do that makes you good’.  He gives many interesting examples – the Beatles, Bill Gates etc – but I was wondering could this be applied to DBAs ? If it takes 10,000 hours to be a really elite DBA – how long does that really take ? 8 hours a day makes 1250 days. If we assume that most DBAs work around 230 days a year – then it takes around 5 and a half years to become an elite DBA.   But how much time per day does a DBA spend actually doing DBA work ? Certainly it’s my experience that the more experienced I get as a DBA, the less time I seem to spend actually doing DBA work – ie meetings, change-control meetings, project planning, liasing with other teams, appraisals etc.  Is it more accurate to assume that a DBA spends half their time actually doing ‘real’ DBA work – or is that just my bad luck ?   So, in reality, I’d argue it can take at least 5 1/2 and more likely closer to 10 years to become an elite DBA. Why do I keep receiving CVs for senior DBAs with 2-4 years actual DBA experience ? In the second section I found particularly interesting, Gladwell writes about analysis of plane crashes and the importance of in-cockpit communications. He describes a couple of crashes involving Korean Airlines – where co-pilots were often deferrential to pilots, and unwilling to openly criticise their more senior colleagues or point out errors when things were going badly wrong… There’s a better summary of Gladwell’s concepts on mitigation  here – but to apply this to a DBA role… If you are a DBA and you do not agree with  a decision of one of your superiors, then it’s your duty as a DBA to say what you think is wrong, before it’s too late…  Obviously there’s a fine line between constructive criticism and moaning, but a good senior DBA or manager should be able to take well-researched criticism\debate from a more junior DBA.   Is this really possible ?

• No network connectivity (not wired or wireless) - RT5390

  - by Ben Udy

  I am starting to think I simply need to accept a small loss and sell my new ASUS K73E. Because I really don't enjoy computing when I have to deal with Windough$ and this windows 7 64 bit on my new ASUS is even worse than the old machines with XP. I have written to ASUS and they simply say "We don't support Linux" and while Ralink's website says they do support Linux I can't get anyone to tell me what model Ralink card might be in my machine. Is anyone out there who might be able to give me some useful advice????

I have now gone to Ralink.com and downloaded (via Windows 7) the driver package (it is a bz2 file). I hope I can figure out how to install it. And FYI - I was not able to run su (not authorized?) and dmidecode didn't exist (probably needs to be downloaded BUT no internet yet in Ubuntu)

• Reduce weight in healthy way - Day 2

  - by krnites

  My second day of reducing weight and it seems most of the blog are correct in saying that you can reduce weight if your calorie consumption is less than what you burn. In one day I have lost 1 lbs without doing anything. My current weight is 177.4 lbs. Yesterday I ate small portion of dinner that I used to eat that also around 7 PM. Normally I eat my dinner around 10 PM and withing 2 hour of eating I go for sleep, but yesterday I ate around 7 PM and went for sleep only after 12.On my second day I have eaten noodles and 3 eggs in breakfast and sesame chicken ( I love it) and fried rice in lunch, I still have not gone for running but had plan to go for running and then swimming. I hope it will at least burn the calories that I had taken. On some site it was written that a normal men body needs around 2000 Calorie a day. So if I am eating less than 2000 calorie ( noodles + 3 eggs = 400+200, rice + sesame chicken = 1300, total = 1900) and burning around 300 calorie, my total calorie intake will be 1600 which is less than what my body needs. So most probably by tomorrow I should come under 176 lb bracket.Apart from counting the calorie that I am taking in everyday and approx number of calorie that I am burning everyday, I had also starting tracking my physical activities on my mobile. I have got a beautiful Samsung Focus S Windows 7.5 mobile. And after browsing through the market I have downloaded couple of health Apps.1. 6 Week training - this has set of exercise and lets you choose the number of sets you want to do for all exercise. Its focus on your core muscles.2. Fast food Calories - This apps has all the fast food chain listed and give the calorie count of each of the food item available on there menu. Like for Burger King's French Fries Large (Salted) contains 500 Calorie.3. Gym Pocket Guide - Contains instructions for different kind of exercise and tells a right way of doing them.4.  RunSat - kind of GPS based application. Its mark the distance you have run, shows the path you have taken on a map, total calorie burnt, laps completed. I love this apps.5. Stop Watch I also have noticed that If I am running in GYM and have television in front of me where a movie or serial is going on which I like,  I normally didn't notice the time. Most of the time running on treadmill is very boring, but if some music video is playing or some kind of sitcom is going, I can run for  a hour or half.So on day 2 I have lost 1 lbs and had learnt that calorie intake should be less then calorie burnt for a given day.

• Software Tuned to Humanity

  - by Phil Factor

  I learned a great deal from a cynical old programmer who once told me that the ideal length of time for a compiler to do its work was the same time it took to roll a cigarette. For development work, this is oh so true. After intently looking at the editing window for an hour or so, it was a relief to look up, stretch, focus the eyes on something else, and roll the possibly-metaphorical cigarette. This was software tuned to humanity. Likewise, a user’s perception of the “ideal” time that an application will take to move from frame to frame, to retrieve information, or to process their input has remained remarkably static for about thirty years, at around 200 ms. Anything else appears, and always has, to be either fast or slow. This could explain why commercial applications, unlike games, simulations and communications, aren’t noticeably faster now than they were when I started programming in the Seventies. Sure, they do a great deal more, but the SLAs that I negotiated in the 1980s for application performance are very similar to what they are nowadays. To prove to myself that this wasn’t just some rose-tinted misperception on my part, I cranked up a Z80-based Jonos CP/M machine (1985) in the roof-space. Within 20 seconds from cold, it had loaded Wordstar and I was ready to write. OK, I got it wrong: some things were faster 30 years ago. Sure, I’d now have had all sorts of animations, wizzy graphics, and other comforting features, but it seems a pity that we have used all that extra CPU and memory to increase the scope of what we develop, and the graphical prettiness, but not to speed the processes needed to complete a business procedure. Never mind the weight, the response time’s great! To achieve 200 ms response times on a Z80, or similar, performance considerations influenced everything one did as a developer. If it meant writing an entire application in assembly code, applying every smart algorithm, and shortcut imaginable to get the application to perform to spec, then so be it. As a result, I’m a dyed-in-the-wool performance freak and find it difficult to change my habits. Conversely, many developers now seem to feel quite differently. While all will acknowledge that performance is important, it’s no longer the virtue is once was, and other factors such as user-experience now take precedence. Am I wrong? If not, then perhaps we need a new school of development technique to rival Agile, dedicated once again to producing applications that smoke the rear wheels rather than pootle elegantly to the shops; that forgo skeuomorphism, cute animation, or architectural elegance in favor of the smell of hot rubber. I struggle to name an application I use that is truly notable for its blistering performance, and would dearly love one to do my everyday work – just as long as it doesn’t go faster than my brain.

• Ubuntu 12.10 graphics does not work properly

  - by madox2

  My graphic on ubuntu 12.10 does not work as well as on 12.04. After upgrade I installed driver sudo apt-add-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get install nvidia-current for my Nvidia 450 GTS graphics card. But sometimes I see slight lag on my videos played in VLC player, some of desktop and window effects are lagging, sometimes I can see an indescribable souce of pixels on my screen at the start of ubuntu and so on. I feel difference between 12.04 and 12.10 in favour of former version.

• 6 Ways to Modernize Your Customer Experience

  - by Mike Stiles

  If customers have changed, if the way they research and shop have changed, if their expectations have changed, if their ability to act on dissatisfaction has changed, but your customer experience has NOT changed, what was once “good enough” may now be crippling. Well, the customer has changed, and why wouldn’t they? You’ve probably changed too in your role as consumer. There’s more info available, it’s easier to get, there’s more choice, you’re more mobile, you’re more connected, it’s easier to buy, and yes, it’s easier to switch brands if experiences don’t meet your now higher expectations. Thanks to technological advances, we as marketers can increasingly work borderline miracles. But if we’re still not adamantly adopting customer centricity, and if we aren’t making the customer experience paramount amongst business goals, the tech is wasted. A far more modern customer experience is called for. Here are 6 ways to get there: 1. Modern Marketing: Marketing data is aggregated and targeted to the right customers, who are getting personal, relevant communications. In return, you’re getting insight that finally properly attributes revenue to your marketing efforts. 2. Modern Selling: Demand is being driven across all channels with modern selling tools. Productivity is up thanks to coordinated communication and selling, and performance is ever optimized using powerful analytics. 3. Modern CPQ: You’re cross-selling and upselling more effectively since reps and channel partners have been empowered with the ability to quickly, automatically generate 100% accurate, customer-friendly quotes complete with price controls and automated approvals. 4. Modern Commerce: You’re leveraging data and delivering personalized, targeted digital experiences to everyone. You’re attracting more visitors, and you’re able to scale and keep up with the market and control the experience. 5. Modern Service: You’re better serving your customers by making it easier for them to engage with your brand, plus you’re lowering your costs by increasing agent and tech support efficiencies. 6. Modern Social: You’re getting faster, deeper, more accurate insights from social and turning content around faster, which then goes out to the right people at the right time in the right place. You’ve also gotten proactive in your service, and customers love that. For far too many brands, the buying journey of Need, Research, Select, Buy, Use, Recommend across the multiple connect points of Social, Mobile, Store, Call Center, Site, Ecommerce is a disconnected mess. Oracle’s approach to CX is to connect every interaction your customer has with your brand, avoiding the revenue losses lousy customer experiences bring. How important is the experience to customers? 94% are willing to pay more of their hard-earned money to have better ones, while a meager 1% say they get the good, consistent experiences they expect. Brands, your words aren’t as loud anymore, so your actions as they relate to customer experience are going to have to do the talking. @mikestiles @oraclesocialPhoto: Julien Tromeur, freeimages.com

• iwlwifi on lenovo z570 disabled by hardware switch

  - by Kevin Gallagher

  It was working fine with windows 7. The hardware switch is not disabled. I've toggled it back and forth dozens of times. The wifi light never turns on and it always lists as hardware disabled. I have the latest updates installed. I've been searching for solutions, but none of them seem to work for me. I've tried removing acer-wmi. I've tried setting 11n_disable=1. I've tried resetting the bios. I've tried using rfkill to unblock (only removes soft block). I've rebooted dozens of times. The wifi light turns off as soon as grub loads. Edit: I have a usb edimax wireless nic. It shows hardware disabled as well (although rfkill lists as unblocked). If I unload iwlwifi the usb nic works fine. uname -a `Linux xxx-Ideapad-Z570 3.2.0-55-generic #85-Ubuntu SMP Wed Oct 2 12:29:27 UTC 2013 x86_64 x86_64 x86_64 GNU/Linu`x rfkill list 19: phy18: Wireless LAN Soft blocked: no Hard blocked: yes dmesg [43463.022996] Intel(R) Wireless WiFi Link AGN driver for Linux, in-tree: [43463.023002] Copyright(c) 2003-2011 Intel Corporation [43463.023107] iwlwifi 0000:03:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 [43463.023190] iwlwifi 0000:03:00.0: setting latency timer to 64 [43463.023253] iwlwifi 0000:03:00.0: pci_resource_len = 0x00002000 [43463.023257] iwlwifi 0000:03:00.0: pci_resource_base = ffffc900057c8000 [43463.023261] iwlwifi 0000:03:00.0: HW Revision ID = 0x0 [43463.023797] iwlwifi 0000:03:00.0: irq 43 for MSI/MSI-X [43463.024013] iwlwifi 0000:03:00.0: Detected Intel(R) Centrino(R) Wireless-N 1000 BGN, REV=0x6C [43463.024250] iwlwifi 0000:03:00.0: L1 Enabled; Disabling L0S [43463.045496] iwlwifi 0000:03:00.0: device EEPROM VER=0x15d, CALIB=0x6 [43463.045501] iwlwifi 0000:03:00.0: Device SKU: 0X50 [43463.045504] iwlwifi 0000:03:00.0: Valid Tx ant: 0X1, Valid Rx ant: 0X3 [43463.045542] iwlwifi 0000:03:00.0: Tunable channels: 13 802.11bg, 0 802.11a channels [43463.045744] iwlwifi 0000:03:00.0: RF_KILL bit toggled to disable radio.

• Why is multithreading often preferred for improving performance?

  - by user1849534

  I have a question, it's about why programmers seems to love concurrency and multi-threaded programs in general. I'm considering 2 main approaches here: an async approach basically based on signals, or just an async approach as called by many papers and languages like the new C# 5.0 for example, and a "companion thread" that manages the policy of your pipeline a concurrent approach or multi-threading approach I will just say that I'm thinking about the hardware here and the worst case scenario, and I have tested this 2 paradigms myself, the async paradigm is a winner at the point that I don't get why people 90% of the time talk about multi-threading when they want to speed up things or make a good use of their resources. I have tested multi-threaded programs and async program on an old machine with an Intel quad-core that doesn't offer a memory controller inside the CPU, the memory is managed entirely by the motherboard, well in this case performances are horrible with a multi-threaded application, even a relatively low number of threads like 3-4-5 can be a problem, the application is unresponsive and is just slow and unpleasant. A good async approach is, on the other hand, probably not faster but it's not worst either, my application just waits for the result and doesn't hangs, it's responsive and there is a much better scaling going on. I have also discovered that a context change in the threading world it's not that cheap in real world scenario, it's in fact quite expensive especially when you have more than 2 threads that need to cycle and swap among each other to be computed. On modern CPUs the situation it's not really that different, the memory controller it's integrated but my point is that an x86 CPUs is basically a serial machine and the memory controller works the same way as with the old machine with an external memory controller on the motherboard. The context switch is still a relevant cost in my application and the fact that the memory controller it's integrated or that the newer CPU have more than 2 core it's not bargain for me. For what i have experienced the concurrent approach is good in theory but not that good in practice, with the memory model imposed by the hardware, it's hard to make a good use of this paradigm, also it introduces a lot of issues ranging from the use of my data structures to the join of multiple threads. Also both paradigms do not offer any security abut when the task or the job will be done in a certain point in time, making them really similar from a functional point of view. According to the X86 memory model, why the majority of people suggest to use concurrency with C++ and not just an async approach ? Also why not considering the worst case scenario of a computer where the context switch is probably more expensive than the computation itself ?

• Best Language for the job? Database | C++, .NET, Java

  - by Randy E

  Ok, quick overview. I'm pretty brand new to software design. I have experience reading and editing/customizing PHP things for online scripts/software; Such as CMS, Wordpress, some forum solutions. I'm about to begin my degree in Software Design, the school I'm going to will allow us to kind of focus on an area, C++, Java, or .NET. I've played around a little with VB over the past week, mostly just trying to get a slight feel for it, however nothing extensive. I've been through Herbert Schildt's "C++, A Beginner's Guide." but I was mainly reading it, not doing anything with it beyond a couple basic Console Apps (and getting frustrated with auto-close :/ ). Now, where I decide to focus more in with my degree will depend on what the best language for the job is for my first piece of software I want to develop on my own. Assume I haven't looked at any of the languages at all, please help with the following: My first piece of software will be a database program. Everything has to do with users inputting and retrieving data, and calling that data to help with another function of the software, automatically calculating billing information based on information inputted in the other portion of the program. I won't go into too many details as I'm targeting a niche that doesn't have too much competition, but the competition that is there is established. I want to offer more features, scalable solutions, and the ability to port it to an online version. Ok, basically, it is a complete case management with integrated billing for Private Investigators. I would like the case management to be able to check the Database to see if certain information has been inputted before (such as Names/SSN's), and then the billing will pull hours inputted in the case portion for investigative work, multiplying by an already inputted amount for the fee, and then calculate sales tax. I also want to provide potential clients with an easily scalable solution, that is, a basic option for start ups that costs the least amount, with no additional users, ran on one machine. A middle option with the ability to create users and place them in two groups (User or Admin), as well as adding a few additional features, ran on one machine, but this will allow it to be accessed after being mapped on a network drive. And a third option to allow the placement into 4 different groups (Investigators, Billing, Managers, Admins) and more features. And then, a couple of years after launch, a 4th option that is browser based allowing the same 4 groups to login, as well as clients (view things concerning their case, with some admin customizable objects that can be added for clients view), over the internet. The only licensing security I would like to employ right off the bat will be serial key generated after ordering online (received in an email after the successful purchase). The program will access a database stored on a server periodically to verify license. I would like it to be able to check to make sure it's the most updated version and automatically update if not.

• Why is my laptop so sluggish? Or Damn You Facebook and Twitter! Or All Hail Chrome!

  - by John Conwell

  In the past three weeks, I've noticed that my laptop (dual core 2.1GHz, 2Gb RAM) has become amazingly sluggish.  I only uses for communications and data lookup workflows, so the slowness was tolerable.  But today I finally got fed up with the suckyness and decided to get to the root of the problem (I do have strong performance roots after all). It actually didn't take all that long to figure it out.  About a year ago I converted to Google Chrome (away from FireFox).  One of the great tools Chrome has is a "Task Manager" tool, that gives you Windows Task Manager like details for all the tabs open in the browser (Shift + Esc).  Since every tab runs in its own process, its easy from Task Manager (both Windows or Chrome) to identify and kill a single performance offending tab.  This is unlike IE, where you only get aggregate data about all tabs open.  Anyway, I digress.  Today my laptop sucked.  Windows Task Manager told me that I had two memory hogging Chrome tabs, but couldn't tell me which web page those tabs are showing.  Enter Chrome Task Manager which tells you the page title, along with CPU, memory and network utilization of each tab.  Enter my amazement.  Turns out Facebook was using just shy of half a Gb of RAM.  Half a Gigabyte!  That's 512 Megabytes!524,288 Kilobytes! 536,870,912 Bytes!  Or 4,294,967,296 Bits!  In other words, that's a frackin boat load of memory.  Now consider that Facebook is running on pretty much 96.3% (statistics based on absolutely nothing) of every house hold desktop, laptop, netbook, and mobile device in America, that is pretty horrific! And I wasn't playing any Facebook games like FarmWars or MafiaVille.  I just had my normal, default home page up showing me who just had breakfast, or just got finished with their morning run. I'm sorry...let me say that again...HALF A GIG OF RAM!  That is just unforgivable. I can just see my mom calling me up:  Mom: "John...I think I need a new computer.  Mine is really slow these days" John: "What do you have running?" Mom: "Oh, just Facebook" John: "Ok, close Facebook and tell me how fast your computer feels" Mom: "Well...I don't know how fast it is.  All I do is use Facebook" John: "Ok Mom, I'll send you a new computer by Tuesday" Oh yea...and the other offending web page?  It was Twitter, using a quarter of a Gigabyte. God I love social networks!

• Unity Dash and top toolbar won't open after updating to 12.10

  - by pgrytdal

  Today, I updated to Ubuntu 12.10. After re-starting, like the updater suggested, the toolbar on the top of the screen, and the dash won't load. I seem to be missing other features, as well, like alttab to switch windows, etc. I am able to access the Terminal, by typing CtrlAltT, which is how I was bale to access Firefox. How do I fix this problem? Edit: 2:10 PM on 10/19/12 As Chris Carter suggested, I'm including the results of the teminal command lspci (Sorry...

• Does the method of adjustment matter, or just the final calibration?

  - by Steve

  A company produces software (and hardware) that is used to both perform automatic adjustments on electronic test equipment as well as perform calibrations of the same equipment. The results of the calibrations are put onto a certificate of calibration that is sent to the customer along with the equipment. This calibration certificate states various conditions of the calibration, such as what hardware (models/serial numbers) and software (version) was used to perform the calibration, as well as things like environmental conditions, etc. Making the assumption that the software used to produce the data (and listed on the calibration certificate) used on the certificate of calibration must have gone through a "test/release" process and must be considered "released" software - does this also mean that the software used for adjustment must also be released? I believe that the method (software/environmental conditions/etc) used or present during adjustment doesn't matter, all that really matters is the end result of the calibration, the conditions present during the calibration, and whether or not the equipment was within the specifications. The real question I'm hoping to get answered: Is there a reputable source (e.g. NIST or somewhere similar) that addresses this question? (I have searched...) The thinking is that during high volume production runs, the "unreleased" system can be used to perform adjustments, as long as a released system is used to perform the calibrations, since the time required to perform the adjustments is much longer than the calibration. This unreleased system will eventually become released for use, but currently is not. Also, please not that there is a distinction between "adjustment" and "calibration". The definition from BIPM International vocabulary of metrology, 2.39: Operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties (of the calibrated instrument or secondary standard) and, in a second step, uses this information to establish a relation for obtaining a measurement result from an indication. Followed by NOTE 2 (emphasis in original text): Calibration should not be confused with adjustment of a measuring system, often mistakenly called "self-calibration", nor with verification of calibration As a side note, I'm not sure why this got down voted. It's regarding software and it's use before and after release for use. I believe there is a best practice that can be applied and this is (hopefully) not primarily opinion based.

• Ubuntu 12.04 share the internet over WiFi from wvdial?

  - by Sour Lemon

  I have just installed Ubuntu 12.04 on a separate partition on my hard drive so I can dual boot to either Windows 7 or Ubuntu. I am living in Japan and so I'm using a mobile broadband USB device called "Softbank C02LC". By default it seems that this device isn't recognised so I did the following: Terminal: sudo su nano /usr/bin/usbModemScript Nano: #!/bin/bash echo 1c9e 9900 > /sys/bus/usb-serial/drivers/option1/new_id Terminal: chmod +x /usr/bin/usbModemScript nano /etc/udev/rules.d/option.rules Nano: ATTRS{idVendor}=="1c9e", ATTRS{idProduct}=="9900", RUN+="/usr/bin/usbModemScript" ATTRS{idVendor}=="1c9e", ATTRS{idProduct}=="9900", RUN+="/sbin/modprobe option" which made the device visible from the network manager etc. However even though I set up my details correctly when I created a new connection (Correct username, APN etc) as soon as I try to connect it almost immediately disconnects. Because of this I then followed the instructions at this site: http://debugitos.main.jp/index.php?Ubuntu%2F%A5%E2%A5%D0%A5%A4%A5%EB%A5%A4%A5%F3%A5%BF%A1%BC%A5%CD%A5%C3%A5%C8 And I ended up using the c02lc_connect script at the bottom of the page to connect to the internet. The file contains the following bash script: #!/bin/sh usbinterfece=/dev/ttyUSB2 VID=1c9e PID=9900 WRONG_PID=f000 LSUSB=/usr/sbin/lsusb GREP=/bin/grep MODPROBE=/sbin/modprobe SWITCH=/usr/sbin/usb_modeswitch SWITCH_D=/etc/usb_modeswitch.d WVDIAL=/usr/bin/wvdial SLEEP=/bin/sleep SUDO=/usr/bin/sudo WHICH=/usr/bin/which switch_config="$SWITCH_D/$VID:$WRONG_PID" if ! [ -x $WVDIAL -a -x $SWITCH ]; then echo "Install wvdial and usb_modeswitch." exit 0 fi check_usb() { local vid="$1" local pid="$2" ($LSUSB | $GREP "$vid:$pid") } if ! (check_usb "$VID" "$PID"); then echo "Cannot find modem device..." if (check_usb "$VID" "$WRONG_PID") && ( [ -f "$switch_config" ] ); then echo "The device is attached but its mode is wrong." echo "Try usb_modeswitch..." $SUDO $SWITCH -c "$switch_config" $SLEEP 1 if (check_usb "$VID" "$PID"); then echo "Successfully switched the mode." else echo "Failed to switch the mode..." exit 1 fi else exit 1 fi fi if [ ! -c "$usbinterface" ]; then $SUDO $MODPROBE usbserial vendor=0x$VID product=0x$PID $SLEEP 2 fi $SUDO $WVDIAL which works completely fine - no problems what-so-ever. But we also have 1 more laptop here which I need to share the internet connection with. In Windows 7 I do this with the Connectify program, and in Ubuntu I have seen that you can do things like set up hotspots etc. But because I am using WvDial I am not sure how I would share the internet. I am only beginning to use Ubuntu but unfortunately until I can figure out how to share the internet over WiFi when connected via WvDial I have to stick with Windows. If you have any ideas on how to do this it would be much appreciated!

• Why does the login screen fail to appear?

  - by a different ben

  My system: Dell Precision T3500 nVidia Quadro NVS 295 Ubuntu 12.04 x86_64 (3.2.0-32) Essential problem: On boot my system won't get past the splash screen. I can switch to another virtual terminal and log in, I can also ssh from another system -- so it appears that the problem might be with the display manager. How can I diagnose and fix this problem? More info: From a VT I can issue sudo lightdm restart, and this will bring up the login screen and and I can continue from there. So I do have access to my system. Update-manager recently updated a number of packages, including a bunch of x11 and xorg packages, some nVidia drivers, rpcbind, etc etc. My boot log (if that is any guidance) says the following: fsck from util-linux 2.20.1 fsck from util-linux 2.20.1 fsck from util-linux 2.20.1 fsck from util-linux 2.20.1 rpcbind: Cannot open '/run/rpcbind/rpcbind.xdr' file for reading, errno 2 (No such file or directory) rpcbind: Cannot open '/run/rpcbind/portmap.xdr' file for reading, errno 2 (No such file or directory) /dev/sda1: clean, 597650/1525920 files, 3963433/6103296 blocks /dev/sda7: clean, 11/6406144 files, 450097/25608703 blocks /dev/sda5: clean, 158323/1525920 files, 1886918/6103296 blocks /dev/sda8: clean, 250089/107929600 files, 111088810/431689728 blocks Skipping profile in /etc/apparmor.d/disable: usr.bin.firefox Skipping profile in /etc/apparmor.d/disable: usr.sbin.rsyslogd * Starting AppArmor profiles [80G [74G[ OK ] Loading the saved-state of the serial devices... /dev/ttyS0 at 0x03f8 (irq = 4) is a 16550A * Starting ClamAV virus database updater freshclam [80G [74G[ OK ] * Starting Name Service Cache Daemon nscd [80G [74G[ OK ] * Starting modem connection manager[74G[ OK ] * Starting K Display Manager[74G[ OK ] * Starting mDNS/DNS-SD daemon[74G[ OK ] * Stopping GNOME Display Manager[74G[ OK ] * Stopping K Display Manager[74G[ OK ] * Starting bluetooth daemon[74G[ OK ] * Starting network connection manager[74G[ OK ] * Starting Postfix Mail Transport Agent postfix [80G [74G[ OK ] speech-dispatcher disabled; edit /etc/default/speech-dispatcher * Starting VirtualBox kernel modules [80G [74G[ OK ] * Starting the Winbind daemon winbind [80G [74G[ OK ] saned disabled; edit /etc/default/saned * Starting anac(h)ronistic cron[74G[ OK ] * Stopping anac(h)ronistic cron[74G[ OK ] * Checking battery state...

• Need help identifing what resources (eg. In MIT OpenCourseWare) can help me prepare for a test [closed]

  - by jiewmeng

  I am entering uni soon. I can sit for a placement test to see if I elegible for exemptions. The details are http://www.comp.nus.edu.sg/undergraduates/TestScope11_12.html Or CS2100 Computer Organisation (please click title) The objective of this module is to familiarise students with the fundamentals of computing devices. Through this module students will understand the basics of data representation, and how the various parts of a computer work, separately and with each other. This allows students to understand the issues in computing devices, and how these issues affect the implementation of solutions. Topics covered include data representation systems, combinational and sequential circuit design techniques, assembly language, processor execution cycles, pipelining, memory hierarchy and input/output systems. Recommended Textbooks Digital Design: Principles and Practices [DDPP] by John F. Wakerly, Prentice-Hall. ISBN 0-13-324500-4. Computer Organizations and Design (The hardware/software interface) by David A. Patterson and John L. Hennessy. CS2105 Introduction to Computer Networks (please click title) This course aims to provide a broad introduction to computer networks and some appreciations of network application programming. It covers a range of topics including basic data communication and computer network concepts, protocols, networked computing concepts and principles, network applications development and network security. The emphasis of teaching is on the working principles and application of computer networks. As an integral part of the course, tutorials and practical assignments enforcing learning will also be given. These assignments provide an early exposure in network application programming and they should be able to complete by using personal computers and school's network facilities. Topics included: An overview of computer networks and the Internet Basic data communications Application layer Transport layer Network layer and routing Link layer and local area networks Recommended Textbook James F. Kurose & Keith W. Ross, Computer networking: A top-down approach featuring internet, Addison Wesley, 2001 I am wondering what resources eg. MIT OpenCourseWare or other universities resources are available to help he perpare for these particular modubles. I am thinking does the Networking one look like CCNA? The computer oragization. Its like electronics, assembly etc? I learnt some electronics in Poly but looking at the sample papers, uni looks very different... I have about 1 month to prepare if I want any chance of exempting from these modules :) any help?

• Cheese won't start

  - by Anthony Hohenheim

  I can't start Cheese Webcam Booth. It starts loading and there is a brief moment when the window shows up but then it disappears, like it shuts itself down and it's not in system monitor. My webcam works perfectly in Skype video call. I installed and run Camorama and it gave me an error: Could not connect to video device (/dev/video0) Please check connection When I run the lsusb I get this line for my webcam: Bus 002 Device 002: ID 04f2:b210 Chicony Electronics Co., Ltd And for my graphic card, running lspci: VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) It's not a pressing matter, but it bugs my nerves, if it works on Skype, why does Cheese and other programs refuse to run. As I said, it's not a big deal but any help would be appreciated. Running Cheese in terminal: (cheese:11454): Gtk-WARNING **: Attempting to add a widget with type GtkImage to a GtkToggleButton, but as a GtkBin subclass a GtkToggleButton can only contain one widget at a time; it already contains a widget of type GtkLabel (cheese:11454): Gtk-WARNING **: Attempting to add a widget with type GtkImage to a GtkToggleButton, but as a GtkBin subclass a GtkToggleButton can only contain one widget at a time; it already contains a widget of type GtkLabel (cheese:11454): Gtk-WARNING **: Attempting to add a widget with type GtkImage to a GtkToggleButton, but as a GtkBin subclass a GtkToggleButton can only contain one widget at a time; it already contains a widget of type GtkLabel (cheese:11454): Gtk-WARNING **: Attempting to add a widget with type GtkHBox to a GtkButton, but as a GtkBin subclass a GtkButton can only contain one widget at a time; it already contains a widget of type GtkLabel (cheese:11454): Gtk-WARNING **: Attempting to add a widget with type GtkImage to a GtkButton, but as a GtkBin subclass a GtkButton can only contain one widget at a time; it already contains a widget of type GtkLabel (cheese:11454): Gtk-WARNING **: Attempting to add a widget with type GtkHBox to a GtkToggleButton, but as a GtkBin subclass a GtkToggleButton can only contain one widget at a time; it already contains a widget of type GtkLabel (cheese:11454): Gtk-WARNING **: Attempting to add a widget with type GtkImage to a GtkButton, but as a GtkBin subclass a GtkButton can only contain one widget at a time; it already contains a widget of type GtkLabel (cheese:11454): Gdk-WARNING **: The program 'cheese' received an X Window System error.

To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.)

• Using the @ in SQL Azure Connections

  - by BuckWoody

  The other day I was working with a client on an application they were changing to a hybrid architecture – some data on-premise and other data in SQL Azure and Windows Azure Blob storage. I had them make a couple of corrections - the first was that all communications to SQL Azure need to be encrypted. It’s a simple addition to the connection string, depending on the library you use. Which brought up another interesting point. They had been using something that looked like this, using the .NET provider: Server=tcp:[serverName].database.windows.net;Database=myDataBase; User ID=LoginName;Password=myPassword; Trusted_Connection=False;Encrypt=True; This includes most of the formatting needed for SQL Azure. It specifies TCP as the transport mechanism, the database name is included, Trusted_Connection is off, and encryption is on. But it needed one more change: Server=tcp:[serverName].database.windows.net;Database=myDataBase; User ID=[LoginName]@[serverName];Password=myPassword; Trusted_Connection=False;Encrypt=True; Notice the difference? It’s the User ID parameter. It includes the @ symbol and the name of the server – not the whole DNS name, just the server name itself. The developers were a bit surprised, since it had been working with the first format that just used the user name. Why did both work, and why is one better than the other? It has to do with the connection library you use. For most libraries, the user name is enough. But for some libraries (subject to change so I don’t list them here) the server name parameter isn’t sent in the way the load balancer understands, so you need to include the server name right in the login, so the system can parse it correctly. Keep in mind, the string limit for that is 128 characters – so take the @ symbol and the server name into consideration for user names. The user connection info is detailed here: http://msdn.microsoft.com/en-us/library/ee336268.aspx Upshot? Include the @servername on your connection string just to be safe. And plan for that extra space…
