• Why can't I install 10.04 on a system that already has 8.04?

  - by Android Eve

  Ubuntu 10.04 is beautiful. I love it. I am dying to install it on my PC, alongside the existing Ubuntu 8.04 (from which I write this message right now). But... it won't let me! When I reach the partitioning stage (manual!) Ubuntu 10.04 sees my two HDDs as one RAID volume. It doesn't see all the partitions I already have in place in /dev/sda and /dev/sdb. Even Windows 7 doesn't behave like this... (yes, I actually managed to install Windows 7 64-bit in dual-boot configuration with Ubuntu 8.04 on this same system). Note: GParted on Ubuntu 10.04 (live CD) sees the partition intended for Ubuntu 10.04 (/dev/sda4) perfectly, but is unable to format it. Note: I also removed that partition trying to reformat it via GParted once 10.04 LiveCD is loaded. It didn't help. I believe that the problem lies in Ubuntu "deciding for me" that the HDDs should be "seen" as a RAID, hence any partition is seen by GParted as "busy" or "locked". Any idea how to solve this problem?

• Two graphical entities, smooth blending between them (e.g. asphalt and grass)

  - by Gabriel Conrad

  Supposedly in a scenario there are, among other things, a tarmac strip and a meadow. The tarmac has an asphalt texture and its model is a triangle strip long that might bifurcate at some point into other tinier strips, and suppose that the meadow is covered with grass. What can be done to make the two graphical entities seem less cut out from a photo and just pasted one on top of the other at the edges? To better understand the problem, picture a strip of asphalt and a plane covered with grass. The grass texture should also "enter" the tarmac strip a little bit at the edges (i.e. feathering effect). My ideas involve two approaches: put two textures on the tarmac entity, but that involves a serious restriction in how the strip is modeled and its texture coordinates are mapped or try and apply a post-processing filter that mimics a bloom effect where "grass" is used instead of light. This could be a terrible failure to achieve correct results. So, is there a better or at least a more obvious way that's widely used in the game dev industry?

• Video on Hyperion Tax Provision

  - by Lia Nowodworska - Oracle

  ( in via Jan) EPM Information Development has asked us to remind you about the new video available for Hyperion Tax Provision. You can view it on the OracleEPMWebcasts YouTube channel here: http://bit.ly/1jxLlCy An information rich 4:40 minutes of your time.  So please take a look. The video gives a brief overview of the main features of  Hyperion Tax Provision. You will learn ... That Tax Provision and reporting System builds on the Hyperion Financial Close Reporting Platform That much of the Tax Provision flow process is similar to the Financial Close Process and that the modules have been aligned to work together very closely. That HTP enables you to integrate Book- and Tax Reporting on a common platform. That It uses the technology of HFM, ties in with SmartView and can be used with Hyperion Financial Reporting. That the native integration between the Financial System and the Tax System creates transparency for the Tax Departments and removes bottlenecks in the tax process. More technical information can be found here: Oracle Hyperion Tax Provision Data Sheet Oracle Hyperion Tax Provision White Paper Oracle Hyperion Tax Provision Documentation If you have another 45 minutes to spare and want to get into greater detail, then you can check out the recording of an Advisor Webcast that we did earlier last year: You can find this via KM Doc Oracle Business Analytics Advisor Webcast Schedule and Archive Recordings (Doc ID 1456233.1) -> Select the Tab "Archived 2013" and it is the third from the top: "Oracle Hyperion Tax Provision - Features and Overview with Demo" If you have questions towards that Advisor Webcast, you may participate in the Community Discussion about it.

• How to troubleshoot problems sharing internet connection via WiFi on Mac OS X

  - by sprugman

  I'm at a hotel, plugged into their network via ethernet on my MacBook. I want to share the connection via wifi to two other computers. I went to Prefs Sharing and set up internet sharing. I know it's working because my friend with a Mac access the net fine. My friend with the PC can see the network, but can't connect to it. In the sharing prefs, airport options, I chose these options: Channel: Automatic Enable encryption: yes WEP Key length 40-bit password length: 5 chars (as specified in the instructional text) Update: I tried it with encryption turned off, and it works. Of course, I'd rather not do that... Any ideas?

• remove disks or other media press any key to restart

  - by Sam I am

  I'm having an issue regarding a disk imaging process. I have a WinPE image that will re-partition, the hard drive, and put a boot-able image on it. When I run the imaging process from an initial state, I get the following error remove disks or other media press any key to restart If I run the process subsequent times, It will work as desired, but I'm still interested in getting the process to work the first time. How do I figure out what's going on here? what should I be looking at? I'm a little bit out of my depth here, I don't know what to do next

• setup advanced filtering and access restrictions on dd-wrt using iptables

  - by Nova deViator

  I have a linksys WRT54GL router with a DD-WRT installed and I want to setup some advanced filtering that seem to not be available through "Access restrictions" web gui option. I guess I would be using IPTABLES then. I have ssh access to router and can run iptables, but I'm not so experienced with iptables. So here are my needs: my policy would be deny all first and then allow exceptions allow all http (port 80) access to WAN through wireless allow all other traffic only to PCs with specific MAC addresses allow internet access to PC with specific MAC address according to schedule (let's say everyday between 18:00-21:00) is this possible to setup with IPtables? could somebody help me a bit with it? or should go and RTFM?

• Find largest value of integer in repeating string

  - by dotancohen

  I have a script log file that looks a bit like this: 2012-9-16 Did something Did 345 things Script time: 244 seconds 2012-9-17 Did yet something Did another thing 23 times Script time: 352 seconds 2012-9-18 Did something special for 34 seconds 51 times Did nothing at all Script time: 122 seconds I would like to find the largest value of N in the lines Script time: N seconds. However, I need to keep the context, so simply removing all lines that don't contain Script time in them is not a viable solution. Currently, I am grepping for lines with Script time, then sorting those to find the highest value, then going back to the original file and searching for that value. However, if there is a more straightforward way then I would love to know. This is on Vim 7.3 on a recent CentOS. I would prefer to remain in VIM if possible. Thanks.

• NetBeans has broken interface with OpenJDK

  - by Krzysztof Stanislawek

  Sorry for English. Usually (say, at 4/5 of times), when I start NetBeans, interface is partially broken. For example, menu items are appearing and at once disappearing after click; some parts of editor are also blocked for cursor actions. Another issue is broken Options window - I can show it only once for NetBeans execution. There are more similar issues. $ java -version java version "1.7.0_55" OpenJDK Runtime Environment (IcedTea 2.4.7) (7u55-2.4.7-1ubuntu1~0.13.10.1) OpenJDK 64-Bit Server VM (build 24.51-b03, mixed mode) Version of NetBeans is 7.0.1. Linux version is Mint 16. I use Mate. I had the same issue at other computer, at the same operating system. I know that installing Sun version of Java could help, but I also know that there shouldn't be such issue with OpenJDK. Also, I had other problem with NetBeans and Sun Java 8 - NetBeans suddenly crashed before he fully started, so I want to stick with OpenJDK. What causes my problem? Should I use other version of NetBeans/OpenJDK?

• Windows XP not able to boot after loading isapnp.sys driver

  - by pragadheesh

  Hi When i power on my DELL Latitude E6400 laptop running on Windows XP SP3, i get a black screen and hangs after that. So I tried to boot through safe mode which hangs after loading the driver isapnp.sys. Doing a bit of googling i found out Windows XP not booting up including safe mode So I loaded my XP boot cd and tried Recovery Console. In the Recovery console, doing "dir" gives the error "an error occurred during directory enumeration". Then i tried chkdsk /p /r which gave "the volume appears to contain one or more unrecoverable problems" How can i fix these please. Thanks in advance.

• Annotating Graphs From Textual Data

  - by steven

  I've got a graph that was generated from a data set that contains: (date, value, annotation) The annotation is a constant value [its either there or is blank] and I would like to add in the third bit of data into the graph I have. An example of this is in the image. The blue line is a graph of the (date, value) graph, and I would like to add in the red dots as graphing (date, annotation@value). Is there an easy way to do this in excel, without having to modify the appearance of the data?

• How do I SCP/FTP to a Coraid SR2421

  - by Pitto

  I need to save data to a Coraid SR2421. I am no expert and I'm trying to understand how this costy piece of hardware works. All I have is a Ethernet cable connecting my laptop and the coraid to a switch and the coraid's console with cursor blinking. Any kind of help would be greatly appreciated. edit and further explanation: I've tried using software on the coraid website but It's not working. So I've contacted the support and they sent me a file to upload on the coraid. It looks like if I upgrade coraid's firmware then I'll be able to use the coraid software on the windows side. That's why I'd need SCP/FTP or any kind of solution to copy a file in the partition that can be read from coraid console command line so I can launch the update command as requested. I hope I was a bit clearer now.

• In an Excel calendar, how can I create a calendar event for a date based on an entry for another date?

  - by James

  Sounds a bit confusing, doesn't it? I've created an 'events calendar' in Excel for my local area. Each date throughout the year is assigned to a row. What I want to do is, when I enter an event for a particular date, then automatically create an entry elsewhere in the calendar for an action to be taken. So for example, There's an event on the 30th July, so I enter it into the calendar. I'd like to be able to specify that an entry should be made 4 weeks earlier, on the 2nd July, to tell me to blog, tweet or whatever about that particular event. Can Excel help me to do that and if so, what do I need to do?

• Scripting language for filling out web form

  - by ityler22

  I have a job as an intern at a technology company, I was given the unfortunate job of performing some data entry into our web management system. The information entered into the web form is stored in a MySQL DB. Upon receiving the data I realized I would have to submit this online form about 1000 different times all consisting of about 10 different text fields / check boxes per form. (So in other words, would be completely mind numbing and be a ridiculous waste of time and resources, or so I thought...) Having used databases a good bit prior to this, my immediate reaction was to just write a short MySQL script to bulk import all of the data, especially since it was already presented to me in an excel spreadsheet ready to go. Thought it may have been some sort of a test since it seemed too obvious. I wrote the script which consisted of about 10 lines of code but was then informed I couldn't be trusted with MySQL Admin privileges to run said script. So my next thought would be to write a script to just enter the information through the web form (Which will take ten times longer but it's what I have to) Being unfamiliar with scripting of this nature (seems like I would need something similar to a bot, but the good kind) I was unsure of how to proceed to do this. Is there a preferred language to use to enter the data i have into the web form I do have access to? I'm not particularly looking for this to be done for me by any means just a nice point in the right direction as far as what scripting language to use and how to pair that with the data I have that needs to be entered. Thanks for the help/ valuable input! EDIT: Is there a way to perform this using perl without having access to place any files on the server? Would I be able to run some Javascript loops to pull the data out of .csv or just a .txt format with line delimiters and insert it into the web form?

• Is learning how to use C (or C++) a requirement in order to be a good (excellent) programmer?

  - by blueberryfields

  When I first started to learn how to program, real programmers could write assembly in their sleep. Any serious schooling in computer science would include a hefty bit of training and practice in programming using assembly. That has since changed, to the point where I see Computer Science degrees with assembly, if included at all, is relegated to one assignment, and one chapter, for a total of two weeks' work out of 4 years' schooling. C/C++ programming seems to have followed a similar path. I'm no longer surprised to interview university graduates who have not spent more than two weeks programming in C++, and have only read of C in a book somewhere. While the most serious CS degrees still seem to include significant time learning and using one or both of the languages, the trend is clearly towards less enforced C/C++ in school. It's clearly possible to make a career producing good work without ever reading or writing a single line of C or C++ code. Given all of that, is learning the two languages worth the effort? Are they at all required to excel? (beyond the obvious, non-language specific advice, such as "a good selection of languages is probably important for a comprehensive education", and "it's probably a good idea to keep trying out and learning new languages throughout a programmers' career, just to stretch the gray cells")

• Choppy USB mice on just one of USB ports

  - by user20532

  I've got Lenovo b560 laptop with latest, properly updated Kubuntu on it (11.04 natty, kernel 2.6.38-8-generic). It has three USB2.0 ports onboard. I usually plug a mouse into one of them (I've got 3 different mice - in office, at home and for when on the go). Sometimes, usually after laptop awakening from sleep, the mouse still works but cursor movements are choppy, as if the processor was extremely loaded (it's usually not). I found that if I re-plug the mouse cord into the other USB port, it works just fine. If I plug it back to problematic port, it is still choppy and remains choppy until next boot. Of course I want my mice to always work fine. Problem is: I cannot reproduce this behavior for sure, it happens sporadically but regularly. I use different USB ports (problem has ever happened on each of them since), I use different mice (each has failed me this way at least once), I cannot generally find what exactly is going wrong and why plugging to different port fixes the mouse instantly. So I'd like to hear at least clues where to look at, what to try to identify my problem. A bit of update: while beginning this post, I had the issue once again. I have just replugged the mouse back to problematic port and it is not recognized at all. On the other port it works smoothly.

• SnapBird Supercharges Your Twitter Searches

  - by ETC

  Twitter’s default search tool is a bit anemic. If you want to supercharge your Twitter search, fire up web-based search tool SnapBird and dig into your past tweets as well as those of friends and followers. Yesterday I was trying to find a tweet I’d sent some time last year regarding my search for an application that could count keystrokes for inclusion in my review of the app I finally found to fulfill the need, KeyCounter. Searching for it with Twitter’s search tool yielded nothing. One simple search at SnapBird and I nailed it. SnapBird requires no authentication to search public tweets (both your own and those of your friends and follows) but does require authentication in order to search through your sent and received direct messages. SnapBird is a free service.

• Understanding IDAT chunk of PNG file format

  - by DRapp

  From the sample image below, I have a border in yellow just for display purposes only. The actual .png file is a simple black/white image 3 pixels by 3 pixels. I was originally thinking to try as a 2x2, but that would not help trying to interpret low/hi vs hi/low drawing stream. At least this way, I would have two black, one white from the top, or one white, two black from the bottom.. So I read the chunks of data, get to the IDAT chunk, decode that (zlib) and come up with 12 bytes as follows 00 20 00 40 00 80 So, my question, how does the above get broken down into the 3x3 black and white sample... Also, it is saved in palette format and properly recognizes the bit depth of 1 and color palette of 2... color pallet[0] is RGBA all zeros. Palette1 has RGBA of 255, 255, 255, 0 I'll eventually get into the multiple other depth formats later, just wanted to start with what would expect to be the easiest. Part II. Any guidance on handling the other depth formats would help if anything special to be considered especially regarding alpha channel (which I am already looking for in the palette) that might trip me up.

• Spreading incoming batched data into a real-time stream

  - by pr1001

  I would like to display some events in 'real-time'. However, I must fetch the data from another source. I can request the last X minutes, though the source is updated approximately every 5 minutes. This means that there will be a delay between the most recent data retrieved and the point in time that I make the request. Second, because I will be receiving a batch of data, I don't want to just fire out all the events down a socket once my fetcher has retrieved it: I would like to spread out the events so that they are both accurately spaced amongst each other and in sync with their original occurrences (e.g. an event is always displayed 6 minutes after it actually happened). My thought is to fetch the data every 5 minutes from the source, knowing that I won't get the very latest data. The original data would be then queued to be sent down the socket 7.5 minutes from its original timestamp – that is, at least ~2.5 minutes from when its batch was fetched and at most 7.5 minutes since then. My question is this: is this the best way to approach the problem? Does this problem have any standard approaches or associated literature related to implementation best-practices and edge cases? I am a bit worried that the frequency of my fetches and the frequency in which the source is updated will get out of sync, leading to points where no data will be retrieved from the source. However, since my socket delay is greater than my fetch frequency, the subsequent fetch should retrieve newer data before the socket queue is empty. Is that correct? Am I missing something? Thanks!

• external display in Ubuntu 13.04

  - by thuc2009

  I have had a look on series of similar topics but I could not find a right answer. Currently, I bought laptop Dell latitude E6530 and installed Ubuntu 13.04 (64 bit) alongside with Windows 7 (I could not get rid of it because of some special programs for work). Ubuntu worked well, however, it did not detect the external displays (Dell 23" and Dell 19") no matter I plugged them before or after booting. Edited: I connected my laptop to those external displays through a laptop dock. I went to Settings- Display, the displays were there, but when I enabled them, Ubuntu logged off automatically. No external display was detected. In addition, the laptop screen sometimes was detected as Dell 23" I got an advice from similar topic that nvidia driver should be updated to version 313 or 319. I upgraded driver and the unity launcher disappeared, main display resolution turned to 640*480 and none of external displays was detected. I tried to use additional drivers, but when I turned it on, it told me that there was no driver to be used. Could some one tell me what should I do ? Edited : options vmwgfx enable_fbdev=1

• Thoughts on type aliases/synonyms?

  - by Rei Miyasaka

  I'm going to try my best to frame this question in a way that doesn't result in a language war or list, because I think there could be a good, technical answer to this question. Different languages support type aliases to varying degrees. C# allows type aliases to be declared at the beginning of each code file, and they're valid only throughout that file. Languages like ML/Haskell use type aliases probably as much as they use type definitions. C/C++ are sort of a Wild West, with typedef and #define often being used seemingly interchangeably to alias types. The upsides of type aliasing don't invoke too much dispute: It makes it convenient to define composite types that are described naturally by the language, e.g. type Coordinate = float * float or type String = [Char]. Long names can be shortened: using DSBA = System.Diagnostics.DebuggerStepBoundaryAttribute. In languages like ML or Haskell, where function parameters often don't have names, type aliases provide a semblance of self-documentation. The downside is a bit more iffy: aliases can proliferate, making it difficult to read and understand code or to learn a platform. The Win32 API is a good example, with its DWORD = int and its HINSTANCE = HANDLE = void* and its LPHANDLE = HANDLE FAR* and such. In all of these cases it hardly makes any sense to distinguish between a HANDLE and a void pointer or a DWORD and an integer etc.. Setting aside the philosophical debate of whether a king should give complete freedom to their subjects and let them be responsible for themselves or whether they should have all of their questionable actions intervened, could there be a happy medium that would allow the benefits of type aliasing while mitigating the risk of its abuse? As an example, the issue of long names can be solved by good autocomplete features. Visual Studio 2010 for instance will alllow you to type DSBA in order to refer Intellisense to System.Diagnostics.DebuggerStepBoundaryAttribute. Could there be other features that would provide the other benefits of type aliasing more safely?

• Apache: Use Specific Applicaion for CGI scripts

  - by RandomInsano

  I have two servers, one in production and one for development. The production server is Solaris, dev is FreeBSD. Because of this, python is installed in different directories. I'm using Python right now for making CGI scripts, and needing to remember to swap my hashbangs when I copy from dev to production is a little annoying (Same issue for SVN updates depending on which server I'm comitting from). Is there a way to configure apache so that I no longer need to hashbangs? Like, if it would lauch python and supply the CGI script for it? Might be a bit of a stretch, but no harm in asking

• Disadvantages of enabling AHCI after Win7 install

  - by Mario De Schaepmeester

  I've formatted my notebook that has a 5400RPM HDD with ~500GB capacity. After installing Windows 7 and about half the drivers (including chipset) I began to doubt whether to go for IDE or AHCI mode for my hard drive. There used to be a lot of discussion on the internet which is better and so far I understood it was particularly helpful on SSDs. Now the general consensus seems to be that AHCI mode is best for most hard drives. I have thus enabled AHCI in the middle of configuring my notebook (rest of the drivers, necessary software etc...) Two questions: considering my HDD's spec above, should I leave it on? Is there any disadvantage of enabling it after Windows 7 and chipset drivers installation? Windows 7 version is 64 bit Home Premium.

• How can browsers in VMs resolve hostnames of websites on parent PC?

  - by elliot100

  I have a number of local websites in development on my Windows PC, set up as virtual hosts within Apache, with hostnames (along the lines of dev.example.com) resolved via the hosts file, so I can test them out them with various browsers. I now want to extend browser testing to running browsers in various OSs in virtual machines, and want to be able to resolve dev.example.com from the VMs. Currently these are a mix of VMWare Server and VirtualPC. I know I can edit the hosts file on any Windows VMs, but this is a bit fiddly and I'd like a solution which is independent of the individual VMs. I think what I need is a nameserver, but what's the simplest way of going about this? I'd like everything to be self-contained on the one machine. I think I can cover firewall and Apache permissioning issues.
