• Image Collector Rips Web Page Images to Your Dropbox Account

  - by Jason Fitzpatrick

  Chrome: Image Collector is a simple Chrome extension that rips the images on the page you’re visiting to your Dropbox (or Google Drive) accounts. Just click the icon, uncheck any images you don’t want it to download, and click save. You can, technically, modify the script to download the images directly to your hard drive, but modifying it was a bit of a hassle and the default save-to-Dropbox action is so smooth we saw little reason to do so.

  - by LAS

  Wacom bamboo connect CTL470 - "no tablet detected ..." I downloaded and attempted to install drivers and software -- I am relatively new in ubuntu and downloaded, extracted,ran in terminal but could not successfully install drivers and software for this device. All of this took up a good deal of space on the drive. Manual compilation failed. I need some help. How do I install so as to use this device? Or please direct me to a suitable (relative beginner) "how to". i have downloaded several packages but the install fails in Software Center and Synaptic.

• ACER Aspire V5-171 compatibility

  - by JamerTheProgrammer

  Im thinking about buying a V5-171 with an i3 in it. Im worried about secure boot though. I heard some people cant turn it off and it wont work... Im not shy to open it up and replace the hard drive with Ubuntu preinstalled. Im also worried about the wifi working. I have heard its been dropping out for people quite a bit along with also the trackpad not working. I dont mind replacing the wifi stick (if its even possible?) inside. Is the GPU (HD4000 i think) supported in ubuntu with full video accel? Thanks!

• Is it possible to power up ports on a USB hub from Ubuntu?

  - by James Henstridge

  I have a D-Link DUB-H7 powered USB 2.0 hub connected to my computer. Occasionally when I reboot the system, I've noticed that some of the ports on the hub get powered down: the green light next to the port is turned off, and the device attached to that port is not visible to lsusb or similar commands. Devices attached to the other ports on the hub function as normal. I am able to restore the ports by disconnecting power to the hub temporarily (from the computer, AC adapter and any devices that might provide any power such as my phone), but this is a bit of a hassle. It seems like something that might be related to power management, so is there some way you can tell the USB hub to power up through software?

• First Windows Phone 7 &ndash; Mobile LOB App.

  - by Richard Jones

  So I spent a couple of hours yesterday building my first Windows 7 Phone Series. application.   I still can’t get used to saying Windows 7 Phone Series.   So I think I’ll just go with WP7.   I must say I’m really impressed.    Calling web-services a breeze laying out User Interface a very straight forward.   I had made called into Dynamics NAV using web-services in under 10 minutes. Working in XAML takes a bit of getting used to,  I’m not trying to-do anything too clever yet. One thing I will point out to transition from one XAML page to the next use this.NavigationService.Navigate(new Uri("/Primary.xaml", UriKind.Relative)); Going from Compact Framework this is equivalent of a Window.Show Its so nice to be able to talk nicely again, about Windows Based Mobile Development!

• Wireless speed drops over time and doesn't get up if not reconnected

  - by Vili Lehto

  I am using Ubuntu 12.10 64bit and I have a Asus PCE-N15 wireless card(in PCI-E slot). The problem is that first when I connect to my WiFi network the speed is just fine, and actually my link speed never drops, it shows a solid 150mb/s+ link speed and good signal. But the download and upload speeds drop dramatically after couple minutes of use and I have to reconnect to fix this. Network is type IEEE 802.11bgn and uses WPA2/AES encryption. I don't have similar problems on the windows side, and the network is working fine on every other device. iwconfig shows this: wlan0 IEEE 802.11bgn ESSID:"WLAN-AP" Mode:Managed Frequency:2.412 GHz Access Point: 00:1E:AB:05:EF:31 Bit Rate=300 Mb/s Tx-Power=20 dBm Retry long limit:7 RTS thr=2347 B Fragment thr:off Encryption key:off Power Management:off Link Quality=61/70 Signal level=-49 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:2 Missed beacon:0 So the question is: Is there a way to fix this? Thanks in advance.

• Periodic clicking sound from PC speaker

  - by John J. Camilleri

  After an update some months ago, my laptop has begun making a low, repeated clicking sound every few seconds. It is not being generated through the regular sound system, as altering the volume and even muting the sound does not make any difference. My regular audio works fine, by the way, so I am guessing this is some sort of PC speaker, since I cannot hear the click when I listen through regular headphones. Strangely, when I open the sound settings dialog the click magically disappears. I don't need to change any settings; if I simply leave the dialog open in the background then the problem disappears. Any ideas what this could be? I am running regular Ubuntu 12.04, and this is the output from lspci -v | grep -A7 -i "audio": 00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02) Subsystem: Acer Incorporated [ALI] Device 0349 Flags: bus master, fast devsel, latency 0, IRQ 44 Memory at 54200000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel Kernel modules: snd-hda-intel

• URL structure for content that is updated daily

  - by Brendon

  A small, simple site I am working on displays a single page with the day's best offers on it. The user is able to move back and forth between previous days. Which of the following URL structures works best? Structure 1 /index.html -- today's best offers /2013-06-29.html -- yesterday's best offers, etc. Structure 2 /index.html -- 302 redirects to /2013-06-30.html (or whatever today is) /2013-06-30.html -- today's best offers /2013-06-29.html -- yesterday's best offers, etc. I quite like structure 2 from the user's point of view (they can share content easily), but I am a bit concerned about updating the redirect from /index.html every single day -- would this perhaps have unintended SEO consequences?

• Does google use chrome to check if a link is used by humans or just there for the bots?

  - by sam

  Does clicking a link in chrome tell google the link is used by humans and there fore not just automated backlink spam. It sounds weird but i read it today on a slightly obscure seo blog, they mensionned clicking the backlinks they make in a version of chrome where they have the "send data annonmusly to google" feature turned on. It sounded a bit far fetched but then i thought it could have a truth to it as with google now looking harder at "spammy" links it would mean at least some humans are using them. Has any one else heard anything else about this ?

• Dev Lop

  - by Jason Franks

  Back in the early 90s, before I was a professional geek--much less a geek with a blog--I saw this old chop socky movie. I don't remember what it was called, or who was in it... all I remember is that, in one scene, the venerable sensei tells the hero: "You must develop your nunchaku technique." This became a bit fo a catchphrase amongst my high school mates. Well folks, I am developing my technuique. This blog has been renamed and the old posts removed--I could go into my reasons for this, but that would defeat the point of the exercise. Sorry if you liked 'em. It has been a good couple of years since I wrote anything here, so I doubt that I am putting out any regular readers. Will I be posting here more often, now that I've renamed and rethemed the place? I don't know. In the meantime, check it out: Bruce Lee playign ping pong with nunchaku. --JF

• Efficiently representing a dynamic transform hierarchy

  - by Mattia

  I'm looking for a way to represent a dynamic transform hierarchy (i.e. one where nodes can be inserted and removed arbitrarily) that's a bit more efficient than using a standard tree of pointers . I saw the answers to this question ( Efficient structure for representing a transform hierarchy. ), but as far as I can determine the tree-as-array approach only works for static hierarchies or dynamic ones where nodes have a fixed number of children (both deal-breakers for me). I'm probably wrong about that but could anyone point out how? If I'm not wrong are there other alternatives that work for dynamic hierarchies?

• Using macro keys with razer blackwidow ultimate 2013

  - by user119020

  I recently bought a Razer blackwidow ultimate 2013 keyboard. The keyboad contains 5 macro keys and according to the manual, they can be quickly set using the key combination fn+f9. However, this doesn't work; it won't record any macros. All the other function buttons on the keyboard work fine (e.g. volume up, volume down, stand-by) Does anyone know how I can enable those keys? Maybe an extra package. I am using 64 bit ubuntu 12.04 Thanks in advance :)

• How Can Someone With Minimum Programming Experience Publish an App of an Existing Program not found in the Software Centre?

  - by Brenton Horne

  There's a free mathematics software that I would like to see in Ubuntu Software Centre, called, 'Sage.' I have minimal experience in programming, so I'm basically here asking if someone could either tell me how to accomplish this without said instructions being completely over my head or if someone could do it for me. For further information here's the sage homepage: http://sagemath.org/ and the .tar.lzma file for its installation is ~500MB and it takes around 2.2 GB on the HDD when installed, I found at least on 32 bit i386 Ubuntu 12.04 LTS. Any help will be greatly appreciated!

• How To Initialize Object Which May Be Used In Catch Clause?

  - by Onorio Catenacci

  I've seen this sort of pattern in code before: //pseudo C# code var exInfo = null; //Line A try { var p = SomeProperty; //Line B exInfo = new ExceptionMessage("The property was " + p); //Line C } catch(Exception ex) { exInfo.SomeOtherProperty = SomeOtherValue; //Line D } Usually the code is structured in this fashion because exInfo has to be visible outside of the try clause. The problem is that if an exception occurs on Line B, then exInfo will be null at Line D. The issue arises when something happens on Line B that must occur before exInfo is constructed. But if I set exInfo to a new Object at line A then memory may get leaked at Line C (due to "new"-ing the object there). Is there a better pattern for handling this sort of code? Is there a name for this sort of initialization pattern? By the way I know I could check for exInfo == null before line D but that seems a bit clumsy and I'm looking for a better approach.

• How do I query the gvfs metadata for a specific attribute?

  - by Mathieu Comandon

  A nice feature in evince is that when you close the program and later reopen the same pdf, it automatically jumps to the page you were reading. The problem I have is that I often read ebooks on several computers and I have to find were I was on the last computer I was reading the pdf. I think syncing these bookmarks in UbuntuOne would be a killer feature for people like me who read pdfs on different computers. By investigating a bit, I found where evince was storing this data, it's in the gvfs metadata and it can be accessed for a particular document by typing gvfs-ls -a "metadata::evince::page" myEbook.pdf Rather that querying a particular file, I'd like to query the whole metadata file (located in ~/.local/share/gvfs-metadata/home for the home directory) for any file where this particular attribute is set to some value. The biggest issue is that gvfs metadata and stored in binary files and we all know it's not easy to get something out of a binary file. So, do you know any way to query the gvfs metadata for some attribute?

• Basic AI FSM - Handling state transition

  - by Galvanize

  I'm starting to study on how to implement game AI, and it seems to me that a very simple FSM for my Pong demo would be a nice way to start. My vision on implementing this would be to have a basic state interface and a class for each state, then the NPC would have an instance of the current state. The class should have an update method and directions on wich state to go next, depending on the event received. The question is: How do I handle this event? Should I have a regular addEventListener and a costum event system? Or should I check on update for the things that could change the current state? I'm feeling a bit lost, I feel I have a good grasp on the FSM concept but a good implementation seems tricky, thanks in advance.

• No boot record when installing 13.04 from USB on WinXP

  - by Phil Leslie

  I'm replacing WinXP with 13.04 on an older PC using wubi.exe on a USB stick. I had no problem changing the BIOS on another system that was a bit newer but when I change the settings on the older PC to boot from USB, I get a DOS message saying "Searching for boot record...Not found" & asked to try again. I don't have the ability to boot from a live CD so is there a reason why I can boot from a USB on a newer computer but can't from an older one? Both have options to choose to boot from USB, but the older one can find no boot record. The system was built on 12/13/01 by American Megatrends. Since I don't have enough "reputation points" to post the screen shot image, you can see it at http://img.photobucket.com/albums/v633/boonevillephil/1029131748-00.jpg.

• Shared hosting banwidth limits

  - by mike

  I have a shared hosting account with a 20GB monthly bandwidth limit. I have exceeded my monthly limit and according to my host my counter is never reset, they say they use a continuous 30 day counter. So for example, I make payment on the 1st of each month, say I use 20GB in the last week of the month. My bandwidth counter is not reset on the 1st of the new month and my bandwidth will only become available in the last week of the new month. Is this common practice by shared hosting companies? Sounds a bit shady to me. Surely my counters should be reset on the 1st of every month when I make payment and 20GB of bandwidth should be available from the day payment is made?

• WUBI installation on Lenovo u310

  - by Tom

  I recently installed 12.04 through the WUBI on a Lenovo u310. The installation went fine, but when I rebooted into Windows 7, and then rebooted into Ubuntu, it immediately went to a command line 'grub' prompt. I was able to reboot from there successfully into 12.04 (once) but then on another occasion could do nothing to reboot into Ubuntu, so had to reinstall. The reason I used the WUBI route was that there are troubles in 12.04 recognizing the hard drives on Lenovo u310 on direct install from memory stick. This has been a bit frustrating, and I was surprised by the difficulties on the Lenovo u310.

  Hello, I'm watching The Bold and the beautiful on the site: http://www.tvp.pl/seriale/obyczajowe/moda-na-sukces/wideo Yesterday I wanted to view next episode, however it didn't work. I checked various episodes from other points in time and none works. The "dots" that appear when a Silverlight video is loading are present, but after them there is only black screen (of death). I'm using Ubuntu Lucid Lynx 32 bit with GNOME2 and firefox 3.6. I have all updates done. Could somebody check if any video is working for them and tell me their setup, please? I'm using Moonlight 3. Two days ago everything was fine but later this problem appeared.

• Strange 401 (Unauthorized) when calling a WCF Service

  - by mipsen

  A WCF Service we call from BizTalk using WCF BasicHTTP usually works fine but all of a sudden it started returning 401 errors for some calls while others continued working as expected so it could not have been a "real" 401. The difference was the size of the message. One parameter of the service is a rather complex object. In the cases we got a 401 it got quite big (containing a lot of customer-data), say 5 MB. So we turned on tracking. The messages we traced out where about 20MB. Not too big for WCF one should suppose... A bit of research led us to increasing maxItemsInObjectGraph in the behaviours but that did not help. The service we call is in the same network as we are and is a WCF service. So we tried changing from BasicHTTP to net.tcp and Bingo! Ok, we had to use CustomBinding in BizTalk to set all the Quotas, etc. but it worked in the end.
