  • Tempescope Displays Weather by Recreating It

    - by Jason Fitzpatrick
    Yesterday we showed you an umbrella stand that signals raining/clear skies by color, today we have something even more interesting: an ambient desktop weather station that recreates the outside weather. The Tempescope pulls down the current weather report from Weather Underground’s API and feeds it to an Arduino board which in turn controls the device. When it’s raining, it pumps water down to simulate rain in the chamber. When there is lightening, LEDs flash. When there is cloud cover, an ultrasonic generator creates a fine mist inside the cylinder. Finally, on sunny days the entire thing glows warmly. To say that we want one would be an understatement. Hit up the link below to read more about the project, the display modes, and to peek inside the device.

  • How can I make the Ubuntu Software Center load?

    I launch it and it goes grey for almost immediately. Closing it prompts me to "force close" and no error report is given.

  • Unmet Dependencies with kdelibs5-data

    - by Jitesh
    I was trying to install Amarok 1.4 on Ubuntu 12.04 (Gnome-classic), by following this instructions. Problem started after giving these two commands dpkg -i kdelibs5-data_4.6.2-0ubuntu4_all.deb dpkg -i kdelibs-data_3.5.10.dfsg.1-5ubuntu2_all.deb Now, immediately after these commands, Ubuntu Updater popped up and gave me an error that the package catalog is broken and needs to be repaired. Nothing can be installed or removed till then. It also offered a suggestion to run apt-get install -f. I tried that, but again got the same error.Also tried apt-get clean followed by apt-get install -f. Again got the following output: jitesh@jitesh-desktop:~$ sudo apt-get clean jitesh@jitesh-desktop:~$ sudo apt-get install -f Reading package lists...

Incidentally, I had first upgraded from 10.04 and had succesfully installed Amarok 1.4 following this same method. But due to other issues, i had to format and do a clean install of 12.04. Now when I tried to install Amarok 1.4, I'm getting these errors. I also have digiKam and k3b installed, if that can be of any help. I use digiKam a lot, so removing KDE is not feasible for me. Any help on this issue will be highly appreciated. Thanks in advance.

  • I'm not sure if this is a valid Ubuntu bug to file

    - by Ian Hincks
    I was in the process of filing an bug on Launchpad, but I had second thoughts because there were so many threatening warnings of the effect, "Don't file a bug report unless you're sure it's a bug, and you should really provide a package name". The problem I have, and I've had it for years, is the following: When I'm installing Ubuntu, it asks me to type in my location before it asks me what my keyboard layout is. Using a QWERTY keyboard but with the buttons popped of and in the Dvorak order, this is annoying, because it is assumes I am using a QWERTY keyboard, and so I have to guess at where all the QWERTY keys are to spell my city's name. It seems like it would make more sense to switch the order of these two questions. (I'll be the first person to admit that this is a very minor problem that has probably wasted less than 2 minutes of my life in total -- but it's the principle of the thing :p) So my question is: is this order there for a particular reason, and if it isn't, is it appropriate to file it as a bug, and under which package name?

  • Why does update-notifier contains system-crash-notification?

    - by int_ua
    I just had "System Program Problem Detected" window appearing several times before user session even started (I have KDM with autologin to locked session). I traced it with xprop to being /usr/lib/update-notifier/system-crash-notification which is binary (while I expected it to be some script) and belongs to update-notifier package (while I expected it to be somewhere from apport*). P.S. Clicking on Report problem... button didn't do anything. $ dpkg -s update-notifier | grep Version Version: 0.147 $ dpkg -L update-notifier | grep system-crash /usr/lib/update-notifier/system-crash-notification $ grep RELEASE /etc/lsb-release DISTRIB_RELEASE=13.10

  • ubuntu cobbler server - importing distros

    - by Stu2000
    I setup and fully configured ubuntu-12.04-server machine with cobbler/dhcp running in about 10 minutes (compared to taking over an hour on centos 5.8). I discovered the cobbler import which appears to be useful. Does this remove the need to use a cobbler distro add? whenever I run a cobbler report after a successful import of ubuntu desktop iso: sudo cobbler import --name=Ubuntu --path=/mnt --breed=debian task started: 2012-12-13_163245_import task started (id=Media import, time=Thu Dec 13 16:32:45 2012) Found a debian/ubuntu compatible signature: pool adding distros avoiding symlink loop avoiding symlink loop avoiding symlink loop associating repos associating kickstarts *** TASK COMPLETE *** I just get the following (nothing): distros: ========== profiles: ========== systems: ========== repos: ========== images: ========== mgmtclasses: ========== packages: ========== files: ========== I was rather hoping that I wouldn't have to do the traditional copying of all files in /mnt to a new /distro directory and then perform a cobbler distro add --initrd=/path/to/inird --kernel=/path/to/kernel Maybe I am mistaken about what the import actually does for me. If someone could elaborate on what the import is actually for please do.

  • Are certification courses worth it?

    - by Bill Williams
    I'm planning on getting certification in Database Development for SQL Server (MSTC - 70-433). I'm a junior level report writer at a new job and the company is offering to pay the majority, if not all, of training course fees. The course is five days. I noticed that MS has a self-paced training kit (book) that I could use. I'm wondering if this would be a better option because it will allow me to go as quick as possible. I've also heard about video training sessions (Lynda.com) but they seem to go at slow pace. My questions are: What should I expect at a certification course? Is it hands-on training? Small classes with personal feedback or not? Would I be better off learning at my own pace using the training kit? (I'd rather this not turn into a certifications are pointless discussion..)

  • Why do programmers write n=O(n^2)?

    - by Jaakko Seppälä
    I studied algorithms in a book Cormen & al. "Introduction to algorithms". In the fourth printing, on the page 43 defines O(g(n))={f(n):there exists positive constants c and n_0 s.t. 0<=f(n)<=cg(n) for all n=n_0} I reported this as a bug in the book www-site because this leads to notation like n=O(n^2) and suggested alternative given in http://www.artofproblemsolving.com/Forum/viewtopic.php?f=296&t=31517&start=20 . It looks like my bug report has not been accepted. Why the programmers won't renew the notation?

  • Why is Google Webmaster Tools crawling invalid URLS and showing 500 errors?

    - by Amos Kane
    Google Webmaster tools is reporting 12k+ 500 errors. Eeek! None of the URLS are valid- they all contain www.youtube.com. First, why is Google crawling these URLS if they don't exist? I supplied a sitemap, and they are of course not in the sitemap. I don't have a robots.txt blocking anything. I've checked for invalid redirects--none, and checked for unclosed tags or something that would throw www.youtube.com into the URL by accident--none. In every 'linked from', the referring URL is also a bad URL, with www.youtube.com in it. The Google Tools report no malware, and I can't check the server logs because the host won't give me access. Really stuck!! Any ideas appreciated!

  • Content theft - Where can I go from here?

    - by Toby
    I am the webmaster of a very successful blog in a fairly small niche. Recently our success has started to bite us with people copying posts on the site without consent and trying to pass them off as their own work. Most sites stop as soon as you contact them but there is one in particular that is a blogger site which persists in passing off our content as their own. Every post we find we report to Google and they have been fairly good at taking the posts offline within a day or two but this isn't good enough or a long term solution. Given the nature of what is being blogged about after 24 hours the post is pretty much useless so I need some way to just stop them from taking our content? Any ideas? I don't want to go down the route of using a third party for people to get our RSS feed but I guess that is one option?

  • Concurrency checking with Last Change Time

    - by Lijo
    I have a following three tables Email (emailNumber, Address) Recipients (reportNumber, emailNumber, lastChangeTime) Report (reportNumber, reportName) I have a C# application that uses inline queries for data selection. I have a select query that selects all reports and their Recipients. Recipients are selected as comma separacted string. During updating, I need to check concurrency. Currently I am using MAX(lastChangeTime) for each reportNumber. This is selected as maxTime. Before update, it checks that the lastChangeTime <= maxTime. --//It works fine One of my co-developers asked why not use GETDATE() as “maxTime” rather than using a MAX operation. That is also working. Here what we are checking is the records are not updated after the record selection time. Is there any pitfalls in using GETDATE() for this purpose?

  • Ubuntu 12.04 "Do nothing" when "lid closed" blanks out external monitor

    - by Elijah Lynn
    This is not the same as this question. I have Ubuntu 12.04 running with an Nvidia card on a W510 Thinkpad. I have one external monitor connected. When I change the power settings to "Do nothing" when "Lid closed" it still keeps the system running which is great. However, it blanks out the display on any external monitors making the system useless. I plan on getting a dock soon and having to identical resolution monitors and would love to be able to dock the monitor and work as normal on the external monitors. Does anyone have a suggestion or fix for this? Should I report this as a bug or feature request?

  • Sample size and statistical significance in Google Analytics

    - by colmcq
    I have been asked to compile a report into dropout rates during checkout for a global webstore I have used a sample size over one month as my sample because: google analytics slows to a crawl over larger sample sizes and makes much of the analysis agonisingly small I believe it to be statistically significant and a representative sample My client has asked me why I didn't use yearly figures and wants proof that one month of data is 'statistically significant'. Am I right in thinking that I need to compare the standard deviation of my monthly sample to the yearly sample and ensure that the deviation is under a certain %age? Question: how do I prove one month of Google Analytics data is representative to one year worth of data? Stats: 90k unique views/month ~1.1m per year.

  • Would installing debugging symbols help for reporting bugs?

    - by Chris
    I'm running a beta version of Ubuntu (12.10) and I've been reporting crashes through apport's automated system. I've glanced at the stacktraces for a couple of the issues and noticed a lot of what look like hex addresses and these: "No symbol table info available." I was wondering if installing the debugging symbols packages from synaptic would provide better information to package maintainers when I report bugs. In other words, would the stacktrace be more useful if I installed those packages? If so, would installing those packages make any (noticeable) performances differences (will my computer run slower)? Thanks, Chris

  • USB Logitech Rumble Pad 2 gamepad AND Thustmaster Universal Challenge Wheel not working in wine

    - by Rick Gionfriddo
    The controller is detected by the OS, and shows up in lsusb, and I can configure it with jstest-gtk, but Live For Speed in Wine doesn't recognize it as connected. Using Lubuntu 12.04, wine version 1.5.5. P.S. - It worked on a previous install of regular Ubuntu 12.04, using the same Wine version. Have tried installing/overriding/un-overriding various DLL's through winetricks to no avail, including xact and dinput8. Since it worked in a previous install of the same version, I figured it was a configuration error, and that I should ask here as opposed to put in a bug report on winehq. EDIT: I just used both controllers in TORCS... why do they work in native games, but not in wine?

  • 81% of European Shoppers Willing to Pay More for Better Customer Experience

    - by Richard Lefebvre
    Customer Experience provides strategic driver for business growth Research released today from Oracle has revealed that customer experience is now a key driver for revenue growth in Europe, and an effective channel for brand differentiation in a globalized economy where products and services are increasingly commoditized. The research report, “Why Customer Satisfaction is No Longer Good Enough,” reveals that 81% of consumers surveyed are willing to pay more for superior customer experience. With nearly half (44%) willing to pay a premium of more than 5%. Improvement of the overall customer experience (40%), providing quick access to information and making it easier for customers to ask questions (35%) were cited as key drivers for spending more with a brand. The pan-European research, carried out in June 2012 by independent research company Loudhouse, surveyed 1400 online shoppers (50% female, 50% male) who had made a complaint or enquiry to a customer service department in the last 12 months.

  • Real life example of an agile game development process

    - by Ken
    I'm trying to learn about applying agile methodologies to game development. But seems to be impossible to find real life examples. What I am looking for are things like; Initial user stories Final user stories (complete, covering the entire game requirements) Acceptance criteria Task list Sprint backlogs (before and after each sprint) The agile books seem to have some limited examples, many of which seem contrived. In this era of open source software, there must be an documented example of the process applied to a game that is publicly available. I am asking specifically about games because they are so different from normal applications. Regular applications are built to all users to complete specific tasks in order to get stuff done(book a room, print a report etc). People play games for much less tangible reasons, so I think the process is significantly different. [it doesn't have to be scrum, it could be any process, just needs to be a real life example game and be reasonably complete]

  • Current iOS version/device statistics?

    - by hotpaw2
    The answer to this SO question has become stale: iOS version/device statistics - where can i find? because time currency wasn't part of that question, and iOS version updates have been release since this question was asked. Is there a web site or other publicly available source which keeps a current or frequently updated list of the percentages of iOS devices and OS versions in use, perhaps by continual monitoring of app analytics or web site logs or other means? And what device or OS information are iOS app analytics currently allowed to report, if any? (...assuming an appropriate privacy policy and adhering to such, of course.)

  • 1 Zettabyte Is Equal to 1 Million Petabytes

    - by Gopinath
    Geeks recently coined a new English term, Zettabyte, to measure the rapidly growing digital information footprint. So what is a Zettabyte? A Zettabyte is equal to 1 million Petabytes or 1 trillion terabytes and 1 quadrillion gigabytes. Symbol To Represent Zettabyte According to wikipedia the symbol ZB is used to represent a Zettabyte. So we can write 10 ZB to represent 10 Zettabytes. Human’s Digital Output Will be 1.2 Zettabytes By End Of 2010 Are you wondering why do we need a term to measure digital data? Tech research firm IDC has recently published a report that estimates current digital footprint created by us so far at 8 million Petabytes – the equivalent of 8,000,000,000,000 GB. This foot print is expected to pass 1.2 Zettabytes by the end of 2010. cc image credit:flickr Join us on Facebook to read all our stories right inside your Facebook news feed.
