• root and home are on seperate partitions, but home still uses up space on root?

  - by Void

  When installing Ubuntu 12.10 for the first time, I made sure /home had it's own partition, gave it about 185GB, and gave root ~10GB. Now root is almost full after a few days and I've noticed that root is as big as /home and some additional MB from some actual root files. Note that I deleted some unused files in /home to make sure it really affects how much space is used in root, and it clearly does. (checked in gparted) I've also made sure the files I am talking about are actually in /home/myname/ and not just in root's home. df -h spits out this information: df: `/root/.gvfs': Permission denied Filesystem Size Used Avail Use% Mounted on /dev/sdb2 9.2G 7.9G 908M 90% / udev 3.9G 12K 3.9G 1% /dev tmpfs 1.6G 932K 1.6G 1% /run none 5.0M 0 5.0M 0% /run/lock none 3.9G 6.4M 3.9G 1% /run/shm none 100M 112K 100M 1% /run/user /dev/sdb3 184G 4.9G 170G 3% /home /dev/sdb4 729G 87G 642G 12% /media/mave/Storage I cut out my windows partitions as I don't see any relevance. I hope this is enough information for someone to tell me what I did wrong

• Default groups for user in Ubuntu 12.10?

  - by Sukminder

  Installed HP Linux Imaging and Printing by using install script and something crashed. Now I'm only member of my own group and lp. Which are the default groups for users in Ubuntu 12.10? Same as this? And, out of curiosity, is there some place where this information is logged? As i.e. some log file showing which groups my user was on previous boot? And/or is this information ,(which groups are default), documented somewhere? OK Found answer. Adding when I'm able (haven't got enough points and have to wait hours to answer myself).

• Fix hibernate on Thinkpad X60 with 12.04 Precise Pangolin

  - by ddaa

  I own a ThinkPad X60, hibernate used to work on 10.04 Lucid Lynx, but no longer works correctly on 12.04. I am aware of how to enable hibernate in Power Manager. The problem here is, in the default configuration, pm-hibernate works, but the system fails to resume correctly. There is no video glitch, black screen or other. The resume process just freezes on the Ubuntu splash boot after a few seconds of disk activity. Is there a way to fix the system configuration so hibernates works again?

• Determining an application's dependencies

  - by gpuguy

  I have developed an application using Windows Forms in C++ (IDE MS VC++ 2010). Some parts of the application also use MFC, and OpenCV. I want to send the application to my cleint for interim testing on his own machine. I have not developed any installer for the application, so I will be sending him an .EXE file. I want the client to not face any difficulties in replicating the environment, and therefore not lose any time. Can somebody suggest me what software (such as MS VC++ Runtime, .NET Framework, Windows SDK, etc.) should be installed on the client's machine for successfull testing of the application? Note: The OS (Windows 7) and hardware are exactly the same on both sides.

• How to ask and acceptalbe question? [closed]

  - by Richard Seitz

  My wife and I own a small art business for the purpose of selling painting. These are paintings done by my wife. We feel because of demand and comments that we should now consider the web to sell our art. How do we start? We already have a registered domain name. We have talked to many people that say they are experts in the design and hosting of webs. What should we ask the potential designer of our web to determine if he/she are professional or just thieves. What does one ask to evaluate the competence and integrity of a web designer? Thank You

• Procedural Planets, Heightmaps and Textures

  - by henryprescott

  I am currently working on an OpenGL procedural planet generator. I hope to use it for a space RPG, that will not allow players to go down to the surface of a planet so I have ignored anything ROAM related. At the momement I am drawing a cube with VBOs and mapping onto a sphere. I am familiar with most fractal heightmap generating techniques and have already implemented my own version of midpoint displacement(not that useful in this case I know). My question is, what is the best way to procedurally generate the heightmap. I have looked at libnoise which allows me to make tilable heightmaps/textures, but as far as I can see I would need to generate a net like this. Leaving the tiling obvious. Could anyone advise me on the best route to take? Any input would be much appreciated. Thanks, Henry.

• Welcome to our Friday tips series!

  - by Chris Kawalek

  Today we're starting a brand new blog series. For your Friday afternoon reading, we'll be posting a technical tip or question and answer on a technical topic. We'll start by introducing ideas on our own, but we'd really like it if you were involved and asked us questions via Twitter! Tag your tweet with #AskOracleVirtualization and we'll consider your question for the blog. Today's tip is on Storage and Oracle Virtual Desktop Infrastructure: Question: I run Oracle Virtual Desktop 3.4.1 on Solaris and use a local ZFS storage pool.  How should I configure my ZFS ARC cache?  Answer by John Renko, Consulting Developer, Oracle: Oracle recommends about 5G of ARC cache per template in use to achieve up to a 90% disk read offload. Set your ARC min=max to reserve the maximum amount of your remaining memory for your running VMs. In /etc/system: set zfs:zfs_arc_min = 5368709120 set zfs:zfs_arc_max = 5368709120 The amount you need to reserve will depend on your template but this has proven to be a great start for a typical windows 7 VM running productivity applications.

• What is the best way to work with large databases in Java depending on context?

  - by user19000

  We are trying to figure out the best practice for working with very large DBs in Java. What we do is a kind of BI (business Intelligence), i.e analyzing very large DBs, and using them to create intermediate DBs that represent intelligent knowledge of the DBs. We are currently using JDBC, and just preforming queries using a ResultSet. As more and more data is being created, we are wondering whether more appropriate ways exist for parsing and manipulating these large DBs: We need to support 'chunk' manipulation and not an entire DB at once(e.g. limit in JDBC, very poor performance) We do not need to be constantly connected since we are just pulling results and creating new tables of our own. We want to understand JDBC alternatives, with respect to advantages and disadvantages. Whether you think JDBC is the way to go or not, what are the best practices to go by depending on context (e.g. for large DBs queried in chunks)?

• Preparing yourself for Code challenges

  - by Daniel Fath

  Just a few days ago I discovered Codility, and I tried their challenges. And I must say. I got my behind handed to me on a platter. I'm not sure what the problem was, but I'll lick my wounds and wait for the solution to come out and compare it with my own. In the meantime, I want to get ready for the next challenge so I'm reading their previous blog posts and seeing how to solve their previous problems. There are a lot of new things I haven't heard about like (Cartesian trees, various sort algorithms, etc.) So, how does one prepare for such challenges (especially the O(x) time and space complexity). What should I read to prepare for such a task?

• Industry average percentage of dev salary spent on tooling? [on hold]

  - by RationalGeek

  I'm trying to budget for my dev shop and compare our budget items to industry expectations. I'm hoping to find some information on what percentage of a dev's salary is generally spent on tooling, both hardware and software. Where can I find such information? If instead there is a source that looks at raw dollars that is useful, too. I can extrapolate what I need from that. NOTE: Your anecdotal evidence from your own job will not be very helpful. I'm looking for industry average statistics from a credible source.

• How can I estimate the entropy of a password?

  - by Wug

  Having read various resources about password strength I'm trying to create an algorithm that will provide a rough estimation of how much entropy a password has. I'm trying to create an algorithm that's as comprehensive as possible. At this point I only have pseudocode, but the algorithm covers the following: password length repeated characters patterns (logical) different character spaces (LC, UC, Numeric, Special, Extended) dictionary attacks It does NOT cover the following, and SHOULD cover it WELL (though not perfectly): ordering (passwords can be strictly ordered by output of this algorithm) patterns (spatial) Can anyone provide some insight on what this algorithm might be weak to? Specifically, can anyone think of situations where feeding a password to the algorithm would OVERESTIMATE its strength? Underestimations are less of an issue. The algorithm: // the password to test password = ? length = length(password) // unique character counts from password (duplicates discarded) uqlca = number of unique lowercase alphabetic characters in password uquca = number of uppercase alphabetic characters uqd = number of unique digits uqsp = number of unique special characters (anything with a key on the keyboard) uqxc = number of unique special special characters (alt codes, extended-ascii stuff) // algorithm parameters, total sizes of alphabet spaces Nlca = total possible number of lowercase letters (26) Nuca = total uppercase letters (26) Nd = total digits (10) Nsp = total special characters (32 or something) Nxc = total extended ascii characters that dont fit into other categorys (idk, 50?) // algorithm parameters, pw strength growth rates as percentages (per character) flca = entropy growth factor for lowercase letters (.25 is probably a good value) fuca = EGF for uppercase letters (.4 is probably good) fd = EGF for digits (.4 is probably good) fsp = EGF for special chars (.5 is probably good) fxc = EGF for extended ascii chars (.75 is probably good) // repetition factors. few unique letters == low factor, many unique == high rflca = (1 - (1 - flca) ^ uqlca) rfuca = (1 - (1 - fuca) ^ uquca) rfd = (1 - (1 - fd ) ^ uqd ) rfsp = (1 - (1 - fsp ) ^ uqsp ) rfxc = (1 - (1 - fxc ) ^ uqxc ) // digit strengths strength = ( rflca * Nlca + rfuca * Nuca + rfd * Nd + rfsp * Nsp + rfxc * Nxc ) ^ length entropybits = log_base_2(strength) A few inputs and their desired and actual entropy_bits outputs: INPUT DESIRED ACTUAL aaa very pathetic 8.1 aaaaaaaaa pathetic 24.7 abcdefghi weak 31.2 H0ley$Mol3y_ strong 72.2 s^fU¬5ü;y34G< wtf 88.9 [a^36]* pathetic 97.2 [a^20]A[a^15]* strong 146.8 xkcd1** medium 79.3 xkcd2** wtf 160.5 * these 2 passwords use shortened notation, where [a^N] expands to N a's. ** xkcd1 = "Tr0ub4dor&3", xkcd2 = "correct horse battery staple" The algorithm does realize (correctly) that increasing the alphabet size (even by one digit) vastly strengthens long passwords, as shown by the difference in entropy_bits for the 6th and 7th passwords, which both consist of 36 a's, but the second's 21st a is capitalized. However, they do not account for the fact that having a password of 36 a's is not a good idea, it's easily broken with a weak password cracker (and anyone who watches you type it will see it) and the algorithm doesn't reflect that. It does, however, reflect the fact that xkcd1 is a weak password compared to xkcd2, despite having greater complexity density (is this even a thing?). How can I improve this algorithm? Addendum 1 Dictionary attacks and pattern based attacks seem to be the big thing, so I'll take a stab at addressing those. I could perform a comprehensive search through the password for words from a word list and replace words with tokens unique to the words they represent. Word-tokens would then be treated as characters and have their own weight system, and would add their own weights to the password. I'd need a few new algorithm parameters (I'll call them lw, Nw ~= 2^11, fw ~= .5, and rfw) and I'd factor the weight into the password as I would any of the other weights. This word search could be specially modified to match both lowercase and uppercase letters as well as common character substitutions, like that of E with 3. If I didn't add extra weight to such matched words, the algorithm would underestimate their strength by a bit or two per word, which is OK. Otherwise, a general rule would be, for each non-perfect character match, give the word a bonus bit. I could then perform simple pattern checks, such as searches for runs of repeated characters and derivative tests (take the difference between each character), which would identify patterns such as 'aaaaa' and '12345', and replace each detected pattern with a pattern token, unique to the pattern and length. The algorithmic parameters (specifically, entropy per pattern) could be generated on the fly based on the pattern. At this point, I'd take the length of the password. Each word token and pattern token would count as one character; each token would replace the characters they symbolically represented. I made up some sort of pattern notation, but it includes the pattern length l, the pattern order o, and the base element b. This information could be used to compute some arbitrary weight for each pattern. I'd do something better in actual code. Modified Example: Password: 1234kitty$$$$$herpderp Tokenized: 1 2 3 4 k i t t y $ $ $ $ $ h e r p d e r p Words Filtered: 1 2 3 4 @W5783 $ $ $ $ $ @W9001 @W9002 Patterns Filtered: @P[l=4,o=1,b='1'] @W5783 @P[l=5,o=0,b='$'] @W9001 @W9002 Breakdown: 3 small, unique words and 2 patterns Entropy: about 45 bits, as per modified algorithm Password: correcthorsebatterystaple Tokenized: c o r r e c t h o r s e b a t t e r y s t a p l e Words Filtered: @W6783 @W7923 @W1535 @W2285 Breakdown: 4 small, unique words and no patterns Entropy: 43 bits, as per modified algorithm The exact semantics of how entropy is calculated from patterns is up for discussion. I was thinking something like: entropy(b) * l * (o + 1) // o will be either zero or one The modified algorithm would find flaws with and reduce the strength of each password in the original table, with the exception of s^fU¬5ü;y34G<, which contains no words or patterns.

• Include multiple IP addresses in Google Analytics

  - by RubenGeert

  I sometimes access my own website from my home/work/girlfriend IP addresses. I'd like to create a filter that includes any of these and nothing else. I thought a custom include filter with a very basic regex should do the trick. The regex I use is 62\.58\.32\.193|77\.172\.143\.12$|213\.125\.166\.98 to include 62.58.32.193 and 77.172.143.12 and 213.125.166.98 and no other IP addresses. I obviously tested it before using it. However, pageviews seem to be stuck at zero even though I did generate internal traffic. Does anybody understand what I'm doing wrong?

• Looking for a 24 Hour project for multiple languages [closed]

  - by Daan Timmer

  Right two friends and I came up with this idea of having a 24h programming competition. Where we are going to meet at one place and program away for 24hours long. Though we need a 'project'. Something that needs to be made within 24h. Doesn't have to be a real thing, just a nice learning 'thing'. The rules that we setup for ourselves is that the project can be programmed in any language of our own choice. What I know is that one guy is a PHP enthousiastic, we've got a C#/.NET person. And I am quite easy in languages and speak quite a few (PHP/C#.net/C++STL/Python/JavaScript/Java). Anything really language specific is out of the question. Is there anyone who happens to have a great idea for this?

• Run programs that require a window manager, on the CLI

  - by Twitchy

  Is there any way I can run a game server (MW3) under wine without requiring a window manager present? Currently to run windows only game servers on my Ubuntu box, I have to start them using RDP access as this creates a X session which the program (which has its own GUI). This is a pain as it cannot be automated (or can it?) on start up. What I would rather is some sort of X session emulator that pulls the console output of the program into the CLI so that I can automate server start ups. Is there any program or method that can do this?

• Who makes laptops for Ubuntu?

  - by Tim Lytle

  I'm looking for a laptop and would like to avoid the whole 'is this [specific configuration of hardware] compatible with Ubuntu?' process by finding a laptop manufactured with Ubuntu in mind. I know of system76, but are there any other manufacturers making laptops built to run a standard build of Ubuntu? I'm not counting Dell, as - from my experience - their 'Ubuntu' laptops/netbooks require their build, and because of that have their own set of compatibility issues. UPDATE: And as mentioned in the comments, Dell is no longer selling systems with Ubuntu to consumers.

• How to Organize Subdirectories? [closed]

  - by Gary Iverson

  I am working on my first major (several hundred pages) website design and development project. I want to create subdirectories for each of the website's categories, which in turn have their own subdirectories for easy user navigation. Example: website.com/directory. I am aware that by placing an index.html file within each directory, the browser automatically detects and navigates to that page, but that seems like a messy solution (having multiple index.html files, albeit in distinct folders), and I cannot imagine everyone does that. So my question is...how do you properly organize and use subdirectories?

• How to delete all your old website data from the internet?

  I had my website on rohbits.com but for some reasons I had to delete it and recreate it with this URL wwww.rohbits.com/blog. My problem is that the old links are still visible on google search and when people click on those links, they land on a 404 Error page of the hosting company. I want to either delete all the previous data from the search engines or have an 404 Error page of my own so that I can tell my visitors where the actual website is. I have already redirected all the traffic which comes to rohbits.com to www.rohbits.com/blog but when they click on the expired links, they get this error page.

• Could JQuery and similar tools be built into the browser install?

  - by Ozz

  After reading another question about JQuery and CDN's, is it feasible for tools like JQuery to "come with" the browser, thus reducing/eliminating the need for the first download from a CDN, or from your own host server. JQuery files specifically are pretty small, so you could easily have a number (all?) of the different versions as part of a browser install. Now fair enough, this would increase install footprint, download time for the browser itself. Then sites could check "local" first, before CDN (which then caches), before finally defaulting to downloading from the website server itself. If this is feasible, has it been done, and if not, why hasn't it be done?

• What are my options for Web 2.0 gallery software?

  - by NewProger

  Good day everyone! This is my first post on this site ^_^ My question is: What are my options if I need a Web 2.0 gallery software that work in a very similar manner to this removed web site. Essentially: users can create account, then create and manage their own galleries. And all other users and guests can see these galleries, add tags, comments, etc. Basically a community driven gallery web site. When it comes to "normal" cms I know a lot of good options, but I never worked with any gallery management software... If you can suggest me some good solutions (free) it would be great! Also: If you by any chance know what software is used at this removed website it would be even better, because this solution suits me the best and I would have used this engine, but I cant find any information on what this engine is and if it is even public, or privately developed thing. Thanks in advance!
