• How do I restore the original color scheme, icons, and theme?

  - by katya sehgal

  I'd like the original colour scheme, icon style of 12.04. I somehow lost the Ambiance theme (possible error or upgrade error). I re-installed 'light-themes' from the terminal and got it back. But the panel on the top that shows the options of sound, battery and wi-fi has changed and I can-not get the original setting back. In the windows, the close, minimize tools have shifted to the right instead of the original left side. I had installed MyUnity and Ubuntu Tweak but deleted them. As such, I want the original setting back. Kindly help me with the commands. I have searched for solutions; there are multiple and I need to be sure if I should follow the same. Kindly bear before marking duplicate. Discoveries: The appearance is gray and boxy as outlined here. Not sure same problem. Similar 'gray and boxy' article here. Desktop forgets theme. I have also tried the unity --reset command. It never completes. I gave it 20 minutes.

• Modifying ChangeSet in RIA Services

  - by Mohit

  Hi, I am using RIA Services Beta 2 with Linq2Sql and SL3. In my SL3, I have a datagrid where I can do some mappings of data (Updates, Inserts and Deletes). I override the Submit method when SubmitChanges() is called. In the submit method in the domain service, I do some validation. If a validation fails for a particular ChangeSetEntry in the ChangeSet, a ValidationErrors is added. Then I call the base.Submit(changeSet). So, if the changeset has 3 entities and one of the entities results in validation error, the other 2 entities are also rolled back. It looks like, RIA Services does an implicit transaction and hence it either submits all 3 or none even if 2 out of 3 does not have any validation error. Is there a way for the RIA service, to prevent rollback of the valid entities and only invalidate the ones that has validation failed. Inputs will be appreciated. Thanks Mohit

• Preserving text formatting for dynamic website

  - by Mohit

  Hello Folks, I am facing a problem while creating a dynamic website. I am building it for some pharma company, which have many products. The problem is, every product have different sections of description, and have to be formatted differently. I wanted to store all the product descriptions in the database, but at the same time preserve the formatting of each description. I also plan to provide an admin interface, where they could edit the product information themselves. I could use Joomla or any other CMS for that purpose, but i wanted to know if i want to build such a system of my own, where i could format the text in an editor and them save that thing into database and when i retrieve it, i get the same formatting. How could i do this? Also i wanted to do this in PHP. Thanks -- Mohit

• Fixing windows MBR without Vista Recovery CD

  I had Windows Vista + Ubuntu running on my system. I deleted the ubuntu partitions from Windows. However, when I start the system, GRUB throws up an Error 22 (missing partition) and does not let me boot into Windows. The CD ROM on my laptop is fried and therefore I tried installing Ubuntu again using a USB install. However, the version Ubuntu 9.10 justs hangs in the load screen and does nothing. I do not have windows Vista Recovery CD (as it was a recovery partition in my laptop). What are the options I have? How do I fix this?

• iptables rule to submit packets matching a specific negative rule

  - by Aditya Sehgal

  I am using netfilter_queue to pick up certain packets from the kernel and do some processing on them. To, the netfilter queue, I need all packets from a particular source except UDP packets with src port 2152 & dst port 2152. I try to add the iptable rule as iptables -A OUTPUT ! s 192.168.0.3 ! -p udp ! --sport 2905 ! --dport 2905 -j NFQUEUE --queue-num 0 iptables throw up an error of Invalid Argument. Querying dmesg, I see the following error print ip_tables: udp match: only valid for protocol 17 I have tried the following variation with the same error thrown. iptables -A OUTPUT ! s 192.168.0.3 ! -p udp --sport 2905 --dport 2905 -j NFQUEUE --queue-num 0 Can you please advise on the correct usage of the iptables command for my case.

• Creating Routes using the second NIC in the box

  - by Aditya Sehgal

  OS: Linux I need some advice on how to set up the routing table. I have a box with two physical NIC cards eth0 & eth1 with two associated IPs IP1 & IP2 (both of the same subnet). I need to setup a route which will force all messages from IP1 towards IP3 (of the same subnet) to go via IP2. I have a raw socket capture program listening on IP2 (This is not for malicious use). I have set up the routing table as Destination Gateway Genmask Flags Metric Ref Use Iface IP3 IP2 255.255.255.255 UGH 0 0 0 eth1 If I try to specify eth0 while adding the above rule, I get an error "SIOCADDRT: Network is unreachable". I understand from the manpage of route that if the GW specified is a local interface, then that would be use as the outgoing interface. After setting up this rule, if i do a traceroute (-i eth0), the packet goes first to the default gateway and then to IP3. How do I force the packet originating from eth0 towards IP3 to first come to IP2. I cannot make changes to the routing table of the gateway. Please suggest.

• Four Proven Advantages of Online Learning | Outside Cost, Accessibility or Flexibility

  - by Mohit Phogat

  Coursera believes that online courses complement and supplement traditional education (versus a common misconception online will “replace” traditional.) Our research shows that Coursera’s platform, when used concurrently with a traditional classroom setup, is ideal for “blended learning” (i.e., students watch lectures pre-class, then class-time focuses on interactive work and discussion.) Additionally, we agree with Brad Zomick of SkilledUp—an online learning aggregator—who acknowledges an online course “isn’t an alternative at all but rather a different path with its own rewards.” The advantages of Coursera and our apps for mobile were straightforward and conspicuous from the start: we’re free, open, and flexible to learners’ unique needs and style. Over the past two years, however, the evidence proves there are many more tangible benefits to open, online learning. In SkilledUp’s “The Advantages of Online Courses [Infographic]”–crafted from findings of leading educational research–four observations stand out from the overt characteristics: Speedier Learning - “Research shows that online students achieve same or better learning results in about half the time as those in traditional courses” More Active, Engaged & Motivated - Learners thrive “when working with coursework that is challenging but within their capacity to master.” Tangible Skill Building - with an “improved attitude toward learning” Better Teaching Quality - Courses are taught by experts, with various multimedia and cutting-edge technology, and “are usually better organized than traditional courses” This is only the beginning, Courserians! Everyday we hear your incredible stories on how open online courses enrich your lives and enhance your careers. Meanwhile we study the steady stream of scientific, big-data research proving their worth on a large-scale (such as UPenn’s latest research on the welcomed diversity in Coursera-hosted Wharton MBA courses.) Our motto “Learning without Limits” reminds us that open, online courses give tremendous opportunity to those that might not otherwise have access (or time, or money) to study at a high-caliber institution.

• Why does Ubuntu gets stuck on the loading screen?

  - by mohit

  I've been experiencing many problem lately since I fresh installed Ubuntu 12.04 LTS on my SONY VAIO VPCEH with Windows 7 previously installed. Sometimes when I try to boot Ubuntu, it gets stuck at loading screen. There seems to be some problem with driver (as far I can judge). Following is the log generated, when I press Esc during the boot (before the problem occurs): ... * Stopping System V initialization compatibility [ok] * Starting System V runlevel compatibility [ok] * Starting crash report submission daemon [ok] * Starting automatic crash report generation [ok] ... ... * Starting LightDM Display Manager [ok] Nothing works after that, no Esc, etc, except restart. Also I've observed the following: Inactivity of Hard-drive (Led doesn't glows). Flashing, or blinking, of Caps-lock and Scroll-lock On restart, Ubuntu seem to load successfully. However, the loading screen has somewhat basic graphics. This problem started after I installed Additional drivers: NVIDIA accelerated graphics driver Also, most of the times Ubuntu loads without any problem. However, it is annoying to restart everytime it fails. So my question is: Why this happens and what is the solution?
