• What does it take to successfully run a URL shortener service [on hold]

  - by MxyL

  What are the costs (technology wise) for running a URL shortener service such as bit.ly or anonym.to? For example, if I decided to use an inexpensive shared hosting with "unlimited" bandwidth, would that be feasible? Or would I need a dedicated hosting? I found this question: I want to run a URL shortener for my own usage, what do I need to do?, which makes it easy to set it up, but I'm not too clear what kind of things I need to consider.

• Do you need to know Java before trying Scala

  - by gizgok

  I'm interested in learning Scala. I've been reading a lot about it, but a lot of people value it because it has an actor model which is better for concurrency, it handles xml in a much better way, solves the problem of first class functions. My question is do you need to know Java to understand/appreciate the way things work in Scala? Is it better to first take a stab at Java and then try Scala or you can start Scala with absolutely no java backround?

• how to reset monitor display settings

  - by vector

  On Ubuntu 12.4 laptop with Gnome desktop, I tried to set an additional display through Catalyst (administrative) and slowly ended up making making a mess out of the whole thing. I tried several combinations of settings and at each iterration I just made things worse, ending up with 'mail battery sound time user power' icons repeating on the top bar. Now I'm lost as to how to restore everything to default settings.

• Gnome Shell Thunderbird Mail Notification

  - by Nerdfest

  Does anyone know of a way to get persistent Gnome 3 panel notifications in Gnome 3 in Oneiric? It's one of the few things holding me back from using Gnome 3 regularly. I've actually found a way of moving the notifications from the (usually) hidden bottom bar to the top, but it does not move the Thunderbird icon. The icon also only tends to appear the first time mail is received. I'm very surprised this basic piece of functionality doesn't exist for Gnome Shell.

• How do I change Firefox's `about:config` from a shell script?

  - by James Haigh

  On of the first things I do when first using a fresh Firefox profile, is to set browser.urlbar.trimURLs to false (which really should be changeable though ‘Preferences’ or should have remained default), and to change the search and homepage defaults to DuckDuckGo. Currently I manually go to about:config, click through the angry warning message, and search for the keys (which unlike in DConf Editor, aren't even organised). So I would like to know how to read and write these keys from the command-line so that I can add these tweaks to my customisations script.

• How to use TFS as a query tracking system?

  - by deostroll

  We already use tfs for managing defects in code etc, etc. We additionally need a way to "understand the domain & requirements of the products". Normally, without tfs we exchange emails with the consultants and have the questions/queries answered. If it is a feature implementation we sometimes "find" conflicts in the implementation itself. And when that happens the userstory is modified and the enhancement/bug as per that is raised in TFS. Sometimes it is critical we come back to decisions we made or questions we wanted answers to. Hence we need to be able to track how that "requirement idea" or that "query in concern" evolved. Hence how is it that we can use TFS to track all of this? Do we raise an "issue" item for this? Or do we raise a "bug" item? The main things we'd ideally look in a query tracking system are as follows: Area: Can be a module, submodule, domain. Sometimes this may be "General" - to address domain related stuff, or, event more granular to address modules, sub-modules. Take the case for the latter, if we were tracking this in excel sheets, we'd just write module1,submodule2; i.e. in a comma separated fashion. The things I would like here is to be able search for all queries relating to submodule2 sometime in the future. Responses: This is a record of conversations between the consultant and any other stakeholder. For a simple case, it would just be paragraphs. Each para would start with a name and date enclosed in brackets and the response following that...each para would be like a thread - much like a forum thread Action taken: We'd want to know how the query was closed, what was the input given, what were the changes that took place because of that, etc etc. These are fields I think I would need in such a system apart from some obvious ones like status, address to, resovled by, etc. I am open for any other fields which are sort of important. To summarise my question: how can we manage "queries" in the system? Where should we ideally store data pertaining to those three fields I have mentioned above (for e.g. is it wise to store responses in the history tag assuming we are opening a bug for the query)?

• How to Downgrade Packages on Ubuntu

  - by Chris Hoffman

  Ubuntu’s Update Manager keeps your packages at the latest version, but occasionally a new package version may not work properly. You can downgrade an installed package and lock it at a specific version to prevent it from being updated. This is particularly useful when you run into an updated package with a regression – a bug that prevents things from working properly.

• CMS vs Admin Panel?

  - by Bob

  Okay, so this probably seems like an unusual, more grammar related question, but I was unsure of what to call it. If you use a software such as vBulletin or MyBB or even Blogger and you're the administrator (or other, lesser position such as moderator) of the forum, or publisher/author of the blog, you generally have access to something of an "admin panel". For example, vBulletin's admin panel looks like this and Blogger's admin panel looks something like this. While they both look different and do different things, the goal is fundamentally the same: to provide the user with a method for adding, modifying, or deleting content... to let them control and administrate their forum or blog. Also, they're both made specifically by the company for use in a specific product. Now, there's also options like Drupal. It seems to offer quite a bit more and be quite a bit more generalized. How does something like this work? If you were freelancing, would you deploy a website with Drupal, or would it be something the client might already have installed on their own server? I've never really used Drupal, only heard about it, so please let me know. Also, there seems to be other options like cPanel, a sort of global CMS that allows you to administrate over your entire website. How do those work in comparison to Drupal, or the administrative panels with vBulletin? They seem to serve related, but different purposes. Basically, what is the norm? If I'm developing a web application for a group that needs to be able to edit their website without the need to go into the code or the database (or rather, wants to act in a graphical, easy-to-use content-management/admin panel), would it also be necessary to write my own miniature admin panel? Or would I be able to send them off knowing that they have cPanel? Or could something like Drupal fill this void? Again, I'm a little new to web development, and I'm working on planning out my first, real, large website. So I need a little advice on the standards and expectations for web development - security and coding practices aside, what should I be looking for as far as usability and administration for the client (who will be running the site once I'm done creating the website)? Any extra tips would also be appreciated! Oh, and just a little bit: I'm writing the website using Ruby on the Sinatra framework (both Ruby and Sinatra are things I'm fairly comfortable with) and I'm not being paid to make the website (and I will also be a user, and one of the three administrators of the website) - it's being built for a club I'm in.

• Database Administration as a Service

  A DBA should provide two things, a service and leadership. For Grant Fritchey, it was whilst serving a role in the Scouts of America that he had his epiphany. Creative chaos and energy, if tactfully harnessed and directed, led to effective ways to perform team-based tasks. Then he wondered why these skills couldn't be applied to the workplace. Are we DBAs doing it wrong in the way we interact with our co-workers?

• Booting Ubuntu on HP Pavilion g7 - 13.04 [duplicate]

  - by death2040

  This question already has an answer here: My computer boots to a black screen, what options do I have to fix it? 24 answers I have a HP Pavilion G7 with an AMD A4 processor and Radeon graphics. I want to install Ubuntu on my laptop but whenever I put the Ubuntu live CD in it and boot to it, the screen shows the Ubuntu logo and the four little dots then after about a minute or two the screen goes black. I can tell the screen is still on but it doesn't have anything on it. I'm beginning to wonder if its a driver problem but I can't really install the drivers when I cant even get Ubuntu to show anything except a loading screen. I've already tried using 12.04 and 12.10 and all the others down to Ubuntu 10. none of them worked. All the other versions don't even show the Ubuntu logo. I'd prefer to have Ubuntu 13.04 on it if its possible but I haven't had any luck finding a solution. I've also tried using WUBI installer in Windows 7 but all that did was make my computer slower for windows and it does the same with the screen when i boot it to Ubuntu. I'm trying to use Ubuntu alongside Windows 7. I cant find any solution on Google. It wont load anything and I know that there is a program called grub on Ubuntu that I used on my desktop computer when it had graphics trouble but the trouble with my desktop was minor things like the screen would flash and then show weird patterns on the screen. But I can't find anything on what to do with the HP laptop. Please help. I use this laptop a lot for games on Windows 7 and I just want to use Ubuntu for when I take my laptop to school and for school stuff. Edit: I just tried booting it in nomodeset and some other things and still didn't work. It did boot up but now when it goes to install alongside windows it crashes and says Ubuntu is forcing reboot or something like that Also, this question is different from the black screen at boot issue because when I do use nomodeset on my computer and select install Ubuntu it will go as far as the screen where you can choose to replace Windows or run alongside Windows. Then after I click continue it ejects the live CD and turns off my computer without installing anything. The error message it shows when it ejects the disk says signal 15, shutting down - modem manager [1675]: <info> Caught nm-dispatcher.action: Caught signal 15, shutting down... *Deconfiguring network interfaces... Please remove installation media and close the tray (if any) then press ENTER *Deactivating swap... *Stopping remaining crypto disks... *stopping early crypto disks... unmount: /run/lock: not mounted unmount: /run/shm: not mounted

• Upstart: How does rc job work / order of (contradicting) "start on ..." and "stop on ..." stanzas

  - by Binarus

  Hi, I just can't understand how Upstart's rc job definition in Natty 11.04 works. To illustrate the problem, here is the definition (empty lines and comments are left out): start on runlevel [0123456] stop on runlevel [!$RUNLEVEL] export RUNLEVEL export PREVLEVEL console output env INIT_VERBOSE task exec /etc/init.d/rc $RUNLEVEL Let's suppose we currently are in runlevel 2 and the rc job is stopped (that is exactly the situation after booting my box and logging in via SSH). Now, let's assume that the system switches to runlevel 3, for example due to a command like "telinit 3" given by root. What will happen to the rc job? Obviously, the rc job will be started since it is currently stopped and the event runlevel 3 is matching the start events. But from now on, things are unclear to me: According to the manual $RUNLEVEL evaluates to the new runlevel when the job is started (that means 3 in our example). Therefore, the next stanza "stop on runlevel [!$RUNLEVEL]" translates to "stop on runlevel [!3]"; that means we have a first stanza which will trigger the job, but the second stanza will never stop the job and seems to be useless. Since I know that the Ubuntu / Upstart people won't do useless things, I must be heavily misunderstanding something. I would be grateful for any explanation. While trying to understand this, an additional question came to my mind. If I had contradicting start and stop triggers, for example start on foo stop on foo what would happen? I swear I never will do that, but I am nevertheless very interested in how Upstart handles that on the theoretical level. Thank you very much! Editing the question as a reaction on geekosaur's first answer: I can see the parallelism, but it is not that easy (at least, not to me). Let's assume the job aurrently is still running, and a new runlevel event comes in (of course, the new runlevel is different from the current one). Then, the following should happen: 1) The job is single instance. That means that "start on ..." won't be triggered since the job is currently running; $RUNLEVEL is not touched. 2) "stop on ..." will be triggered since the new runlevel is different from $RUNLEVEL, so the job will be aborted. 3) Now, the job is stopped and waiting. I can't see how it is restarted with the new runlevel. AFAIK, initctl emits events only once, so "start on ..." won't be triggered and the new runlevel won't be entered. I know that I still misunderstanding something, and I am grateful for explanations. Thank you very much!

• Agilist, Heal Thyself!

  - by Dylan Smith

  I’ve been meaning to blog about a great experience I had earlier in the year at Prairie Dev Con Calgary.  Myself and Steve Rogalsky did a session that we called “Agilist, Heal Thyself!”.  We used a format that was new to me, but that Steve had seen used at another conference.  What we did was start by asking the audience to give us a list of challenges they had had when adopting agile.  We wrote them all down, then had everybody vote on the most interesting ones.  Then we split into two groups, and each group was assigned one of the agile challenges.  We had 20 minutes to discuss the challenge, and suggest solutions or approaches to improve things.  At the end of the 20 minutes, each of the groups gave a brief summary of their discussion and learning's, then we mixed up the groups and repeated with another 2 challenges. The 2 groups I was part of had some really interesting discussions, and suggestions: Unfinished Stories at the end of Sprints The first agile challenge we tackled, was something that every single Scrum team I have worked with has struggled with.  What happens when you get to the end of a Sprint, and there are some stories that are only partially completed.  The team in question was getting very de-moralized as they felt that every Sprint was a failure as they never had a set of fully completed stories. How do you avoid this? and/or what do you do when it happens? There were 2 pieces of advice that were well received: 1. Try to bring stories to completion before starting new ones.  This is advice I give all my Scrum teams.  If you have a 3-week sprint, what happens all too often is you get to the end of week 2, and a lot of stories are almost done; but almost none are completely done.  This is a Bad Thing.  I encourage the teams I work with to only start a new story as a very last resort.  If you finish your task look at the stories in progress and see if there’s anything you can do to help before moving onto a new story.  In the daily standup, put a focus on seeing what stories got completed yesterday, if a few days go by with none getting completed, be sure this fact is visible to the team and do something about it.  Something I’ve been doing recently is introducing WIP (Work In Progress) limits while using Scrum.  My current team has 2-week sprints, and we usually have about a dozen or stories in a sprint.  We instituted a WIP limit of 4 stories.  If 4 stories have been started but not finished then nobody is allowed to start new stories.  This made it obvious very quickly that our QA tasks were our bottleneck (we have 4 devs, but only 1.5 testers).  The WIP limit forced the developers to start to pickup QA tasks before moving onto the next dev tasks, and we ended our sprints with many more stories completely finished than we did before introducing WIP limits. 2. Rather than using time-boxed sprints, why not just do away with them altogether and go to a continuous flow type approach like KanBan.  Limit WIP to keep things under control, but don’t have a fixed time box at the end of which all tasks are supposed to be done.  This eliminates the problem almost entirely.  At some points in the project (releases) you need to be able to burn down all the half finished stories to get a stable release build, but this probably occurs less often than every sprint, and there are alternative approaches to achieve it using branching strategies rather than forcing your team to try to get to Zero WIP every 2-weeks (e.g. when you are ready for a release, create a new branch for any new stories, but finish all existing stories in the current branch and release it). Trying to Introduce Agile into a team with previous Bad Agile Experiences One of the agile adoption challenges somebody described, was he was in a leadership role on a team he had recently joined – lets call him Dave.  This team was currently very waterfall in their ALM process, but they were about to start on a new green-field project.  Dave wanted to use this new project as an opportunity to do things the “right way”, using an Agile methodology like Scrum, adopting TDD, automated builds, proper branching strategies, etc.  The problem he was facing is everybody else on the team had previously gone through an “Agile Adoption” that was a horrible failure.  Dave blamed this failure on the consultant brought in previously to lead this agile transition, but regardless of the reason, the team had very negative feelings towards agile, and was very resistant to trying it out again.  Dave possibly had the authority to try to force the team to adopt Agile practices, but we all know that doesn’t work very well.  What was Dave to do? Ultimately, the best advice was to question *why* did Dave want to adopt all these various practices. Rather than trying to convince his team that these were the “right way” to run a dev project, and trying to do a Big Bang approach to introducing change.  He would be better served by identifying problems the team currently faces, have a discussion with the team to get everybody to agree that specific problems existed, then have an open discussion about ways to address those problems.  This way Dave could incrementally introduce agile practices, and he doesn’t even need to identify them as “agile” practices if he doesn’t want to.  For example, when we discussed with Dave, he said probably the teams biggest problem was long periods without feedback from users, then finding out too late that the software is not going to meet their needs.  Rather than Dave jumping right to introducing Scrum and all it entails, it would be easier to get buy-in from team if he framed it as a discussion of existing problems, and brainstorming possible solutions.  And possibly most importantly, don’t try to do massive changes all at once with a team that has not bought-into those changes.  Taking an incremental approach has a greater chance of success. I see something similar in my day job all the time too.  Clients who for one reason or another claim to not be fans of agile (or not ready for agile yet).  But then they go on to ask me to help them get shorter feedback cycles, quicker delivery cycles, iterative development processes, etc.  It’s kind of funny at times, sometimes you just need to phrase the suggestions in terms they are using and avoid the word “agile”. PS – I haven’t blogged all that much over the past couple of years, but in an attempt to motivate myself, a few of us have accepted a blogger challenge.  There’s 6 of us who have all put some money into a pool, and the agreement is that we each need to blog at least once every 2-weeks.  The first 2-week period that we miss we’re eliminated.  Last person standing gets the money.  So expect at least one blog post every couple of weeks for the near future (I hope!).  And check out the blogs of the other 5 people in this blogger challenge: Steve Rogalsky: http://winnipegagilist.blogspot.ca Aaron Kowall: http://www.geekswithblogs.net/caffeinatedgeek Tyler Doerkson: http://blog.tylerdoerksen.com David Alpert: http://www.spinthemoose.com Dave White: http://www.agileramblings.com (note: site not available yet.  should be shortly or he owes me some money!)

• Does use of simple shaders improve performace/battery life?

So i'm thinking about implementing shaders in my game to simplify OpenGL pipeline if it can make better performance. Better performance = better battery life, unless fps is limited by software limit, not hardware power.
