  • ibus symbol disappears for Japanese language selection

    - by Christian Becker-Asano
    Similar to this post No ibus icon in Kubuntu, I have trouble with the ibus icon in Ubuntu 12.04. Each time an update is installed, the language selector for Japanese disappears from the top panel. I need to uninstall and install Japanese again, then reboot, to make the symbol appear again. In this thread No iBus icon in Kubuntu 12.04 the suggestion was to install the Japanese Version of Ubuntu, but is it really true that one has to stick to a special version of Ubuntu to get this problem solved? If so, how can I transfer the settings easily from the current version to the Japanese one?

  • Black screen and blinking cursor for a while during Startup

    - by Soumyadip Mukherjee
    I've installed the Ubuntu 12.04.1 "rock solid" release. Everything works fine apart from the fact that during start-up the usual purple screen and Ubuntu logo doesn't appear. Only a black screen and blinking cursor is visible. Then after a while, for a fraction of a second, the Ubuntu logo and purple screen comes and disappears to the login page. I tried Plymouth but it didn't help in solving the problem. It did end up changing the logo to a more artistic one. Can any one please help? Ubuntu is installed on my ASUS 1225c netbook.

  • Ask the Readers: Are You A Second Screen Multi-tasker?

    - by Jason Fitzpatrick
    Television watchers are no longer keeping their eyes continuously glued to the screen–increasingly smartphone, tablet, and laptop users have merged their mobile device and television time. Are you one of the second screen multi-taskers? Image courtesy of Umani, a TV-companion application for iPad. According to Nielsen user surveys, at least 80% of mobile device owners have used their device while watching television in the past month–27% said they use their mobile device alongside the television multiple times a day. What the survey results are light on, however, is an in depth look at what the users are doing with their second screen. This week we want to hear about whether or not you’re one of the second screen multi-taskers and what you use your mobile device for during your television/movie time. Sound off in the comments and then check back in on Friday for the What You Said roundup.

  • Starting a guest session from the login screen

    - by Odd-rationale
    I was wondering what is the best way to start the guest session from the login screen (GDM). Currently, I created a new user called 'ubuntu-guest' (has to be something other than 'guest'). Then added the following script to the Startup Applications. #!/bin/bash /usr/share/gdm/guest-session/guest-session-launch & /usr/bin/gnome-session-save --logout The problem with this method, is that when you log in as 'ubuntu-guest', you have to start up two gnome sessions: one for 'ubuntu-guest' and one for the actual guest account. Please let me know if you have any other better ideas. Thanks!

  • Ubuntu Oneiric + Awesome WM

    - by janjust
    I upgraded to oneiric ocelot, running awesome wm. Everything works, more or less, fine but one thing I've noticed is that now my menu fonts and my menu symbols are larger than I'd like them to be. I used to set them in font settings, but now (for one I don't even know where font settings are anymore, I tried gnome-tweak-tool) the font-settings are gone? Surely I'm missing something. My prime example is the program evince whose symbols are ginormous. Any hints how to tweak it?

  • genetic algorithm for leveling/build test

    - by Renan Malke Stigliani
    I'm starting o build a online PVP (duel like, one-to-one) game, where there is leveling, skill points, special attacks and all the common stuff. Since I never did anything like that, I'm still thinking about the maths behind the level/skill/special balances. So I thought good way of testing the best/combo builds would implement a Genetic Algorith. It'd be like that: Generate a big portion of random characters Make them fight, level them up accordingly to the victories(more XP)/losses(less XP) Mate the winners, crossing their builds, to try to make even best characters Add some more random chars, emulating new players Repeat the process for some time, or util find some chars who can beat everyone butts So I could play with the math and try to find the balance where the top x% chars would be a mix of various build types. So, is it a good idea, or there are some other easier method to do the balance? PS: I like this also, because it sounds funny

  • Best practice for storing HTML coming from text fields to a database?

    - by user1767270
    I have an application that allows users to edit certain parts of text and then email that out. My question is what is the best way to store this in a Microsoft SQL Server database. Right now I have two tables, one holding the HTML data and one holding the plain text data. When the user saves the info, it replaces newlines with br's and puts it in the HTML-conntaining table and then puts the regular text in the other table. This way the text box has the newlines when they go to edit, but the table that contains the HTML data, has the BR's. This seems like a silly way to do things. What would be the best practice? Thanks.

  • Subscribable World Cup 2010 Calendar

    - by jamiet
    I bang on quite a lot on this blog about ways in which data can get published over the web and one of the most interesting ways, in my opinion, of publishing data in a structured manner that is well understood is to use the iCalendar specification. There isn’t much information in the world that doesn’t have some concept of “when” so iCalendar is a great way of distributing that information. You have probably used iCalendar at some point without even knowing about it. All files with a .ics suffix are iCalendar format files and that is why you can happily import them into Outlook, Hotmail Calendar, Google Calendar etc… where they can be parsed and have the semantic data (when, where and who) extracted from them. Importing of iCalendar format data is really only half the trick though; in my opinion the real value of iCalendar-formatted calendar is the ability to subscribe to them. Subscribing has a simple benefit over importing but that single benefit is of massive importance: a subscriber to an iCalendar calendar can periodically check to see if any updates have been made and, if they have, automatically update the local copy. The real benefit to the user is the productivity gain – a single update to an iCalendar means that all subscribers are automatically made aware of the change and there is zero effort on the part of the subscriber; as my former colleague Howard van Rooijen is fond of saying, “work smarter not harder” – nowhere is this edict more ably demonstrated than subscribing versus importing of calendars. If you want to read some more thoughts about iCalendar then go and read my past blog post Calendar syndication - My big hope for 2009's breakthrough technology or better still go and seek out Jon Udell who speaks very authoritatively on the issue of iCalendar. With this subject of iCalendar on my mind I was interested to discover (via Steve Clayton’s blog post Download the world cup fixtures) that the BBC had made a .ics file available containing all of the matches in the upcoming World Cup. As you can probably guess this was a file that was made available so that it could be imported into your calendar of choice. It had one obvious downside though, right now nobody knows who is going to be playing in the knock-out stages so the calendar looks like this: with no teams being named after 25th June. How much more useful would this calendar have been if the BBC had made it possible to subscribe to the calendar instead, thus the calendar could be updated with the teams for the knock out stages when they are known and every subscriber would have a permanently up-to-date record of all the fixtures in their calendar. Better still, the calendar could be updated with match results as well or perhaps even post a match report from the BBC sport pages; when calendars are made subscribable a sea of opportunity opens up for distribution of information. So with that in mind I have decided to go one better than the BBC. I have imported their .ics into a brand new Hotmail calendar and made it publicly available at the following URLs: HTML http://cid-dc1ed121af0476be.calendar.live.com/calendar/World+Cup+2010/index.html iCalendar webcal://cid-dc1ed121af0476be.calendar.live.com/calendar/World+Cup+2010/calendar.ics The link you’re really interested in is the second one - click on that and it should open up in your calendar software of choice. Or, if you want to view it in an online calendar such as Hotmail Calendar or Google Calendar, copy and paste that URL into the appropriate place. Some people have told me they’re having trouble with the iCalendar link in which case hit the HTML link and then click “View ICS” at the resultant web page: I shall endeavour to keep the calendar updated throughout the World Cup and even if I don’t you’re no worse off than if you had imported the BBC’s .ics file so why not give it a try? If I do keep it up to date then you will have a permanent record of the 2010 World Cup available in your calendar. Forever. If you have your calendar synced to your smartphone then you’ll be carrying match reports around with you without you having to do a single thing. Surely that’s worth a quick click isn’t it?   If you have any thoughts let me have them in the comments below. Thanks for reading. @Jamiet Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • Always use dtexec.exe to test performance of your dataflows. No exceptions.

    - by jamiet
    Earlier this evening I posted a blog post entitled Investigation: Can different combinations of components effect Dataflow performance? where I compared the performance of three different dataflows all working to the same overall goal. I wanted to make one last point related to the results but I thought it warranted a blog post all of its own. Here is a screenshot of one of the dataflows that I was testing: Pretty complicated I’m sure you’ll agree. Now, when I executed this dataflow in the test it was executing in ~19seconds however in that case I was executing using the command-line tool dtexec. I also tried executing inside the BIDS development environment and in that case it took much longer – 139seconds. That’s more than seven times as long. The point I want to make is very simple. If you are testing your dataflows for performance please use dtexec. Nothing else will suffice. @Jamiet

  • Why is design by contract considered an alternative to the pseudo programming process?

    - by zoopp
    Right now I'm reading Code Complete by Steve McConnell and in chapter 9 he talks about the Pseudo Programming Process (PPP). From what I've understood, the PPP is a way of programming in which the programmer first writes the pseudo code for the routine he's working on, then refines it up to the point where pretty much each pseudo code line can be implemented in 1-3 lines of code, then writes the code in the designated programming language and finally the pseudo code is saved as comments for the purpose of documenting the routine. In chapter 9.4 the author mentions alternatives to the PPP, one of which is 'design by contract'. In design by contract you basically assert preconditions and postconditions of each routine. Now why would that be considered an alternative? To me it seems obvious that I should use both techniques at the same time and not chose one over the other.

  • What projects did you have on your CV when you got your first junior web developer job?

    - by CodeNoob
    What sort of projects should one have completed and at what level/standard should these be at before one could justifiably start applying for junior web development jobs? I'm basically trying to find out exactly what other self-taught (front-end or back-end) web-developers have done before they felt they had a realistic chance of getting their first junior development job. I'm hoping for more specific answers than 'I joined an open source project' or 'I did some freelance work'. What was the project? What tasks had you completed on this project?

  • Wait till all CCActions have completed

    - by tGilani
    I am developing a simple cocos2d game in which I want to animate two CCSprites simultaneously, and for this purpose I simply set CCActions on respective `CCSprite's as follows. [first runAction:[CCMoveTo actionWithDuration:1 position:secondPosition]]; [second runAction:[CCMoveTo actionWithDuration:1 position:firstPosition]]; Now I want to wait till the animations are complete, so I can perform the next step. How should I wait for these animations to finish? There are actually two method calls, the first one animates the objects via the code above and second call does the other animation. I need to delay the second method call until the animations in first are complete. (I would not like to use CCCallFunc blocks as I want to call the second method from the same caller as the first one.

  • Role based access control in Oracle VM using Enterprise Manager 12c

    - by Ronen Kofman
    Enterprise Managers let’s you control any element in the environment and define which users can do what on each element. We will show here an example on how to set up RBAC (Role Base Access Control) for Oracle VM using Enterprise Manager, this will be a very simplified explanation  to help you get going. For more comprehensive explanations please refer to the Enterprise Manager User Guide. OK, first some basic Enterprise Manager terminology: Target – any element in the environment is a target – server, pool, zone, VM etc. Administrators – these are the Enterprise Manager users who can login to the platform. Roles – roles are privilege profiles which could be applied to Administrators. The first step will be to discover the virtual environment and bring it in to Enterprise Manager, this process is simple and can be done in two ways: Work on your Oracle VM manager, set it up until you feel comfortable and then register it in Enterprise Manager Use Enterprise Manager and build it all from there. In both cases we will be able to see the same picture from Oracle VM and from Enterprise Manager, any change made in one will be reflected in the other. Oracle VM Manager: Enterprise Manager: Once you have your virtual environment set up in Enterprise Manager it is time to start associating VMs with users (or Administrators as they are called in Enterprise Manager). Enterprise Manager allows us to connect to multiple different identity services and import users from them but the simplest way to add Administrators is just go to setup->security->Administrators and create new Administrator. The creation wizard will walk you through several stages and allow you to assign role(s) to your newly created Administrator, using roles can really shorten the process if done multiple times. When you get to “Target Privileges” stage, scroll down to the bottom to the “Target Privileges” section. In this section you can add targets (virtual machine in our case) and define the type of privileges you would like to assign to the Administrator which you are creating. In this example I chose one of the VMs and granted full privileges to the newly created Administrator. Administrator creation wizard "Target Privileges": Now when you login as the newly created administrator, you will only see the VM that was assign to you and will be able to have full control over it. That’s it, simple and straight forward, Enterprise Manager offers many more things which I skipped here but the point is that if you need role based access control Enterprise Manager can give it to you in a very easy way. Oh and one more thing, virtualization management in Enterprise Manager has no license cost, sweet.

  • Send arbitrary commands to modem for info

    - by mydoghasworms
    I have a USB 3G data card and modem. According to the supplier, to check the data balance on the account, I must dial a number like *89# (or whatever) from the handset. The device appears as a ppp0 interface in my network devices. How does one go about issuing commands to the modem to send the commands and receive back the information? UPDATE: OK, I found some help here: http://www.linuxquestions.org/questions/linux-hardware-18/sending-at-commands-to-a-sms-modem-372445/, but firstly, there are 3 ttyUSB devices on my system, and I assume that one of them is the 3G modem, but how can I tell? Secondly, trying to echo something to two of them says that the device is busy, which stands to reason, because I am using it to connect to the internet. Some help, please?

  • Toyota's Supply Chain "ran too hot"

    - by [email protected]
    The Feb 28th '10 edition of the Economist had a very informative artical (pg.74) on Toyota's over-stretched supply chain pointing out that they were ' the author of most of its own misfortunes".  James Womack is quoted in the piece on Toyota's rapid expansion 'meant working with a lot of unfamiliar suppliers who didn't have a deep understandin of Toyota's culture.  The majority of the problems almost certainly originated not in the Toyota factories but in those of the supppliers'. One purchasing executive said that it started in mid-2008, when the weaker parts of the supply chain were put under great strain. There is a need for visibility but not always there. Firms need transparancy and speed of communications to make sure defective parts and errors dont reach the customer. It concludes with guidance to manufacturers: "It may be safer not to have all your eggs in one basket, but to have maybe 3 suppliers for major components who can benchmark each other' - Toyota was the peerless exemplar, now seen as an awful warning

  • Kernel Panic: line 61: can't open /scripts/functions

    - by Pavlos G.
    I'm facing a problem with all the kernels installed at my system (Ubuntu 10.10 64-bit). Installed kernel versions: 2.6.32-21 up to 2.6.35.23. The booting halted with the following error: init: .: line 61: can't open '/scripts/functions' Kernel panic - not syncing: Attempted to kill init! Pid: 1, comm: init not tainted Only the first one (2.6.32-21) was working up until know. I asked for help at ubuntuforums.org and i was told to check if there's any problem regarding my graphics card (ATI Radeon). I uninstalled all the ATI-related packages as well as all the unecessary xserver-xorg-video-* drivers that were installed. I then rebooted and from then on ALL of the kernels halt with the same error (i.e. it didn't fix the problematic kernels, it just broke the only one that was working...) Any ideas on what i should try next? Thanks in advance. Pavlos.

  • C# XNA - Sky Sphere Question

    - by Wade
    I have been banging my head against the wall trying to get a sky sphere to work appropriately in XNA 4.0. I have the sphere loading correctly, and even textured, but i would like something a little more dynamic that can support a day/night cycle. My issue is that, while i know a good amount of C# and XNA, i know next to nothing about HLSL. (I could make an ambient light shader if my life depended on it...) I also have not been able to find a tutorial on how to build a sky sphere like this. Of course i don't expect to be able to make an amazing one right off the bat, i would like to start small, with a dynamic coloring sky i'll work out the clouds and sun later. My first question: Does anyone know of any good tutorial sites that could help me get a decent grasp around HLSL? Second: Does anyone have a good example of or know where to find one of a gradient sky using XNA and C#?

  • Amanda Todd&ndash;What Parents Can Learn From Her Story

    - by D'Arcy Lussier
    Amanda Todd was a bullied teenager who committed suicide this week. Her story has become headline news due in part to her You Tube video she posted telling her story:   The story is heartbreaking for so many reasons, but I wanted to talk about what we as parents can learn from this. Being the dad to two girls, one that’s 10, I’m very aware of the dangers that the internet holds. When I saw her story, one thing jumped out at me – unmonitored internet access at an early age. My daughter (then 9) came home from a friends place once and asked if she could be in a YouTube video with her friend. Apparently this friend was allowed to do whatever she wanted on the internet, including posting goofy videos. This set off warning bells and we ensured our daughter realized the dangers and that she was not to ever post videos of herself. In looking at Amanda’s story, the access to unmonitored internet time along with just being a young girl and being flattered by an online predator were the key events that ultimately led to her suicide. Yes, the reaction of her classmates and “friends” was horrible as well, I’m not diluting that. But our youth don’t fully understand yet that what they do on the internet today will follow them potentially forever. And the people they meet online aren’t necessarily who they claim to be. So what can we as parents learn from Amanda’s story? Parents Shouldn’t Feel Bad About Being Internet Police Our job as parents is in part to protect our kids and keep them safe, even if they don’t like our measures. This includes monitoring, supervising, and restricting their internet activities. In our house we have a family computer in the living room that the kids can watch videos and surf the web. It’s in plain view of everyone, so you can’t hide what you’re looking at. If our daughter goes to a friend’s place, we ask about what they did and what they played. If the computer comes up, we ask about what they did on it. Luckily our daughter is very up front and honest in telling us things, so we have very open discussions. Parents Need to Be Honest About the Dangers of the Internet I’m sure every generation says that “kids grow up so fast these days”, but in our case the internet really does push our kids to be exposed to things they otherwise wouldn’t experience. One wrong word in a Google search, a click of a link in a spam email, or just general curiosity can expose a child to things they aren’t ready for or should never be exposed to (and I’m not just talking about adult material – have you seen some of the graphic pictures from war zones posted on news sites recently?). Our stance as parents has been to be open about discussing the dangers with our kids before they encounter any content – be proactive instead of reactionary. Part of this is alerting them to the monsters that lurk on the internet as well. As kids explore the world wide web, they’re eventually going to encounter some chat room or some Facebook friend invite or other personal connection with someone. More than ever kids need to be educated on the dangers of engaging with people online and sharing personal information. You can think of it as an evolved discussion that our parents had with us about using the phone: “Don’t say ‘I’m home alone’, don’t say when mom or dad get home, don’t tell them any information, etc.” Parents Need to Talk Self Worth at Home Katie makes the point better than I ever could (one bad word towards the end): Our children need to understand their value beyond what the latest issue of TigerBeat says, or the media who continues flaunting physical attributes over intelligence and character, or a society that puts focus on status and wealth. They also have to realize that just because someone pays you a compliment, that doesn’t mean you should ignore personal boundaries and limits. What does this have to do with the internet? Well, in days past if you wanted to be social you had to go out somewhere. Now you can video chat with any number of people from the comfort of wherever your laptop happens to be – and not just text but full HD video with sound! While innocent children head online in the hopes of meeting cool people, predators with bad intentions are heading online too. As much as we try to monitor their online activity and be honest about the dangers of the internet, the human side of our kids isn’t something we can control. But we can try to influence them to see themselves as not needing to search out the acceptance of complete strangers online. Way easier said than done, but ensuring self-worth is something discussed, encouraged, and celebrated is a step in the right direction. Parental Wake Up Call This post is not a critique of Amanda’s parents. The reality is that cyber bullying/abuse is happening every day, and there are millions of parents that have no clue its happening to their children. Amanda’s story is a wake up call that our children’s online activities may be putting them in danger. My heart goes out to the parents of this girl. As a father of daughters, I can’t imagine what I would do if I found my daughter having to hide in a ditch to avoid a mob or call 911 to report my daughter had attempted suicide by drinking bleach or deal with a child turning to drugs/alcohol/cutting to cope. It would be horrendous if we as parents didn’t re-evaluate our family internet policies in light of this event. And in the end, Amanda’s video was meant to bring attention to her plight and encourage others going through the same thing. We may not be kids, but we can still honour her memory by helping safeguard our children.
