• Moving Forward with Code Iteration

  - by rcapote

  There are times when working on my programming projects, and I get to a point where I'm ready to move on to the next part of my program. However, when I sit down to implement this new feature I get stuck, in a sense. It's not that I don't know how to implement the feature, it's that I get stuck on figuring out the best way to implement said feature. So I sit back for a day or two and let the ideas ferment until I am comfortable with a design. I get worried that I may not write something as well as it could be, or that I might have to go back and rework the whole thing; so I put it off. This is a big reason why I've never really finished many personal projects. Anyone else experience this, and how do you keep your self moving forward in your project?

• Kill a tree, save your website? Content strategy in action, part III

  - by Roger Hart

  A lot has been written about how driving content strategy from within an organisation is hard. And that's true. Red Gate is pretty receptive to new ideas, so although I've not had a total walk in the park, it's been a hike with charming scenery. But I'm one of the lucky ones. Lots of people are involved in content, and depending on your organisation some of those people might be the kind who'll gleefully call themselves "stakeholders". People holding a stake generally want to stick it through something's heart and bury it at a crossroads. Winning them over is not always easy. (Richard Ingram has made a nice visual summary of how this can feel - Content strategy Snakes & ladders - pdf ) So yes, a lot of content strategy advocates are having a hard time. And sure, we've got a nice opportunity to get together and have a hug and a cry, but in the interim we could use a hand. What to do? My preferred approach is, I'll confess, brutal. I'd like nothing so much as to take a scorched earth approach to our website. Burn it, salt the ground, and build the new one right: focusing on clearly delineated business and user content goals, and instrumented so we can tell if we're doing it right. I'm never getting buy-in for that, but a boy can dream. So how about just getting buy-in for some small, tenable improvements? Easier, but still non-trivial. I sat down for a chat with our marketing and design guys. It seemed like a good place to start, even if they weren't up for my "Ctrl-A + Delete"  solution. We talked through some of this stuff, and we pretty much agreed that our content is a bit more broken than we'd ideally like. But to get everybody on board, the problems needed visibility. Doing a visual content inventory Print out the internet. Make a Wall Of Content. Seriously. If you've already done a content inventory, you know your architecture, and you know the scale of the problem. But it's quite likely that very few other people do. So make it big and visual. I'm going to carbon hell, but it seems to be working. This morning, I printed out a tiny, tiny part of our website: the non-support content pertaining to SQL Compare I made big, visual, A3 blowups of each page, and covered a wall with them. A page per web page, spread over something like 6M x 2M, with metrics, right in front of people. Even if nobody reads it (and they are doing) the sheer scale is shocking. 53 pages, all told. Some are redundant, some outdated, some trivial, a few fantastic, and frighteningly many that are great ideas delivered not-quite-right. You have to stand quite far away to get it all in your field of vision. For a lot of today, a whole bunch of folks have been gawping in amazement, talking each other through it, peering at the details, and generally getting excited about content. Developers, sales guys, our CEO, the marketing folks - they're engaged. Will it last? I make no promises. But this sort of wave of interest is vital to getting a content strategy project kicked off. While the content strategist is a saucer-eyed orphan in the cupboard under the stairs, they're not getting a whole lot done. Of course, just printing the site won't necessarily cut it. You have to know your content, and be able to talk about it. Ideally, you'll also have page view and time-on-page metrics. One of the most powerful things you can do is, when people are staring at your wall of content, ask them what they think half of it is for. Pretty soon, you've made a case for content strategy. We're also going to get folks to mark it up - cover it with notes and post-its, let us know how they feel about our content. I'll be blogging about how that goes, but it's exciting. Different business functions have different needs from content, so the more exposure the content gets, and the more feedback, the more you know about those needs. Fingers crossed for awesome.

• Sony bravia screen resolution problem when using Docky

  - by takethemoneyrun

  This is what it looks like: When the laptop (MSI u100) starts up it takes up all available space on the TV screen. About a second after logging in the black bar at the bottom appears. The strange thing is that as you can see the menus can be visible over it, also the dock (Docky app), and any fullscreen application (not maximised, but fullscreen). So what would be the problem here? The source of the problem is the Docky Application. Any ideas?

• Being prepared for a code review as a developer?

  - by Karthik Sreenivasan

  I am looking for some ideas here. I read the article How should code reviews be Carried Out and Code Reviews, what are the advantages? which were very informative but I still need more clarity on the question below. My Question is, Being the target developer, can you suggest some best practices a developer can incorporate before his code is going get reviewed. Currently I practice the following methods PPT for a logical flow Detailed comments. Issue: Even though I have implemented the above practices, they do not help on the review. The problem I faced is, when certain logic is referred, I keep searching for the implementation and the flow and too much time is wasted in the process and I get on people’s nerve. I think a lot of developers would be going through what I am going through as well.

• Ubuntu 12.04 Tenda W322p

  - by Brian Sullivan

  I had a fully operational version of Ubuntu 11.10 running (64 bit) and decided to upgrade to 12.04. After I did I no longer had network connectivity. I am running a Tenda Wireless W322P adapter. In the past I had installed it just fine and it was working great. Everytime I did a kernel update I would always have to do a modprobe rt3562sta to reinstall and get the network working. Now, I do that and I get the error FATAL: Error inserting rt3562sta (/lib/modules/3.2.0-24-generic/kernel/drivers/net/wireless/rt3562sta.ko): Invalid module format I am dead in the water. Any ideas?

• Juju bootstrap, install

  - by Robert G.

  I would like to test MAAS + JUJU + OpenStack (I followed the documentation on maas.ubuntu.org) I already made a test environment: 1 MAAS server wich will also run JuJu 10 KVM servers for Openstack The KVM servers are already in "ready" state in MAAS. I would like to set up JuJu but i could not which is drives me crazy. My environments.yaml: environments: maassrv: type: maas maas-server: 'http://${192.168.1.116}/MAAS/' maas-oauth: 'my-key-from-maas' authorized-keys-path: /root/.ssh/id_rsa.pub admin-secret: 1234 default-series: trusty When I run "juju status -e maassrv` : ERROR Unable to connect to environment "maassrv". Please check your credentials or use 'juju bootstrap' to create a new environment. Error details: environment "maassrv" not found OK, it's right, so i should run juju bootstrap -e maassrv: ERROR environment "maassrv" not found When i run the command without the -e switch: error: no environment specified So, I am stuck here, I already added the required ssh keys to maas too. I ran out of ideas why it isn't working.

• Shell command slow when using pipe, fast with intermediate file

  - by plang

  Does anyone understand this huge difference in processing time, when using an intermediate file, or when using a pipe? I'm converting tiff to pdf using standard tools on a fresh debian squeeze server. A standard way of doing this is to convert to ps first. Without pipe: root@web5:~# time tiff2ps test.tif > test.ps real 0m0.860s user 0m0.744s sys 0m0.112s root@web5:~# time ps2pdf13 -sPAPERSIZE=a4 test.ps > test.pdf real 0m0.667s user 0m0.612s sys 0m0.060s With pipe: root@web5:~# time tiff2ps test.tif | ps2pdf13 -sPAPERSIZE=a4 - > test.pdf real 1m6.098s user 0m15.861s sys 0m50.9 During the last command, gs process is at 100% all the time. Update: Here is an strace output for the ps generation: root@web5:~# strace tiff2ps test.tif > test.ps execve("/usr/bin/tiff2ps", ["tiff2ps", "test.tif"], [/* 28 vars */]) = 0 brk(0) = 0x1395000

• Can't get past the Ubuntu loading screen when installing

  - by Oscar Godson

  I'm trying to install Ubuntu 11.04 onto some custom made PC that my father in law tried building. It had Windows on it, but he wants Ubuntu so he asked me to do it. I've installed Ubuntu 11.04 on a few computers no issues, but on this computer I get to the all purple screen with the Ubuntu logo and the orange and white dots that light up. Like this: The fan is also super, super loud and sounds like the whole thing is going to explode and has been running like this for 15 mins ish. Then, after about 15 mins the dots stop animating from orange to white and usually just stick at all orange. Any ideas?

• Sound problems in Unity - input but no output

  - by ana

  I am new to Ubuntu, having just installed it for the first time on my Lenovo Thinkpad. Since I installed it I have no sound output whatsoever. However, I can see from the graphical interface in Sound Preferences Input that the sound input appears to be working correctly. I have tried the following: https://help.ubuntu.com/community/HdaIntelSoundHowto https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules ubuntu-bug audio I have two sound cards, cat card0/codec* | grep Codec Codec: Conexant CX20585 Codec: Conexant ID 2c06 cat card1/codec* | grep Codec Codec: Nvidia GPU 0b HDMI/DP Codec: Nvidia GPU 0b HDMI/DP Codec: Nvidia GPU 0b HDMI/DP Codec: Nvidia GPU 0b HDMI/DP And now have pretty much run out of ideas.

• What is a fast way to darken the vertices I'm rendering?

  - by Luis Cruz

  To make a lighting system for a voxel game, I need to specify a darkness value per vertex. I'm using GL_COLOR_MATERIAL and specifying a color per vertex, like this: glEnable(GL_COLOR_MATERIAL); glBegin(GL_QUADS); glColor3f(0.6f, 0.6f, 0.6f); glTexCoord2f(...); glVertex3f(...); glColor3f(0.3f, 0.3f, 0.3f); glTexCoord2f(...); glVertex3f(...); glColor3f(0.7f, 0.7f, 0.7f); glTexCoord2f(...); glVertex3f(...); glColor3f(0.9f, 0.9f, 0.9f); glTexCoord2f(...); glVertex3f(...); glEnd(); This is working, but with many quads it is very slow.. I'm using display lists too. Any good ideas in how to make vertices darker?

• Can't connect VPN/add new VPN connection on 12.04 when using NX

  - by dbotamous

  I remote control my Ubuntu box using NX. I am trying to create a new VPN connection. I click on Configure VPN ? Add ? OpenVPN ? Create then I get a "Editing VPN connection 1" window but everything is grayed out, and I can't edit it. The only button I can click is Cancel. The reason I bring up NX is because if I plug in a monitor keyboard and mouse, I can create, edit import VPN connections just fine. So I imported all the different VPN connections, everything was fine. I then remoted back into the Ubuntu machine with NX, click on my VPN connection, and get VPN Connection Failed - The VPN CONNECTION failed to start. Not authorized to control networking. I then disconnected and reconnected NX, and now all the VPN connections I had imported are gone. Any ideas?

• Which useful alternative control structures do you know?

  - by bigown

  Similar question was closed on SO. Sometimes when we're programming, we find that some particular control structure would be very useful to us, but is not directly available in our programming language. What alternative control structures do you think are a useful way of organizing computation? The goal here is to get new ways of thinking about structuring code, in order to improve chunking and reasoning. You can create a wishful syntax/semantic not available now or cite a less known control structure on an existent programming language. Answers should give ideas for a new programming language or enhancing an actual language. Think of this as brainstorming, so post something you think is a crazy idea but it can be viable in some scenario. It's about imperative programming.

• Bumblebee - Poor performance with games

  - by user106880

  I have an Alienware M14x (GeForce 650m with Optimus) and got Bumblebee working correctly (trying to get ready for steam for linux :)). Also I'm running Ubuntu 12.10 with Unity. I get great framerates with glxgears and sauerbraten (a game on the repositories), but when I run games like Bastion and Splice, I get pretty terrible framerate, in fact worse than my integrated intel gpu. I have nvidia-current installed under ubuntu-x-swat/x-updates so it's driver version 310.xx. Also I forgot to add that I haven't been able to test other drivers because they seem to break glx (x can't load the glx module). I've been troubleshooting this for days now, and I'm very nearly out of ideas. Any hints on why only some games are running so poorly with bumblebee?

• How to get pngcrush to overwrite original files?

  - by DisgruntledGoat

  I've read through man pngcrush and it seems that there is no way to crush a PNG file and save it over the original. I want to compress several folders worth of PNGs so it would be useful to do it all with one command! Currently I am doing pngcrush -q -d . *.png then manually cut-pasting the files from the tmp directory to the original folder. So I guess using mv might be the best way to go? Any better ideas?

• How do I install Pencil?

  - by Rich

  Pencil either runs as a Firefox extension or as a standalone application with XULRunner 1.9.2. Trying to install XULRunner: rich@rich-laptop:~/apps/pencil$ sudo apt-get install xulrunner-1.9.2 [sudo] password for rich: Reading package lists... Done Building dependency tree Reading state information... Done Package xulrunner-1.9.2 is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'xulrunner-1.9.2' has no installation candidate So I tried to install it using Firefox by clicking on the install button on the Pencil home page, and the .xpi file was downloaded and opened by an archive manager. Any ideas?

• mp3 file streaming/download - apache server memory issue

  - by Manolis

  I have a website, in which users can upload mp3 files (uploadify), stream them using an html5 player (jplayer) and download them using a php script (www.zubrag.com/scripts/). When a user uploads a song, the path to the audio file is saved in the database and i'm using that data in order to play and show a download link for the song. The problem that i'm experiencing is that, according to my host, this method is using a lot of memory on the server, which is dedicated. Link to script: http://pastebin.com/Vus8SRa7 How should I handle the script properly? And what would be the best way to track down the problem? Any ideas on cleaning up the code? Any help much appreciated.

• Setting effects variables in XNA

  - by Badescu Alexandru

  Hello ! I am currently reading a book named "3D Graphics with XNA Game Studio 4.0" by Sean James and have some questions to ask : If i create a effect parameter named lets say SpecularPower and have in my effect a variable named SpecularPower , if i do something like effect.Parameters["SpecularPower"].SetValue(3) That wil change the SpecularPower variable in my effect ? And a second question, not regarding the book : If i have a spaceship and i've created a "boost" functionality that speeds up my spaceship, what effects should i implement to create the impresion oh high speed ? I was thinking of making everything except my spaceship blurry but i think there would be something missing . Any ideas ? Regards, Alex Badescu

• Morgan Stanley chooses Solaris 11 to run cloud file services

  - by Frederic Pariente

  At the EAKC2012 Conference last week in Edinburg, Robert Milkowski, Unix engineer at Morgan Stanley, presented on deploying OpenAFS on Solaris 11. It makes a great proofpoint on how ZFS and DTrace gives a definite advantage to Solaris over Linux to run AFS distributed file system services, the "cloud file system" as it calls it in his blog. Mike used ZFS to achieve a 2-3x compression ratio on data and greatly lower the TCA and TCO of the storage subsystem, and DTrace to root-cause scalability bottlenecks and improve performance. As future ideas, Mike is looking at leveraging more Solaris features like Zones, ZFS Dedup, SSD for ZFS, etc.

• What is a best practice tier structure of a Java EE 6/7 application?

  - by James Drinkard

  I was attempting to find a best practice for modeling the tiers in a Java EE application yesterday and couldn't come up with anything current. In the past, say java 1.4, it was four tiers: Presentation Tier Web Tier Business Logic Tier DAL (Data Access Layer ) which I always considered a tier and not a layer. After working with Web Services and SOA I thought to add in a services tier, but that may fall under 3. the business logic tier. I did searches for quite a while and reading articles. It seems like Domain Driven Design is becoming more popular, but I couldn't find a diagram on it's tier structure. Anyone have ideas or diagrams on what the proper tier structure is for newer Java EE applications or is it really the same, but more items are ranked under the four I've mentioned?

• International multi-OS keyboard layout for both coding and surfing?

  - by rassie

  So yes, the problem has been raised in parts multiple times already. Still I'm looking for a keyboard layout that has the following features: Easy on fingers (Dvorak-like layouts welcome) Easy for coding Includes german characters (typing ä with AltGr-p is not ok). Works well with web-browsing (Ctrl-t and Ctrl-w on one hand, left one very much preferred, since that's where my ex-CapsLock, now Ctrl lies) Works well with default Emacs bindings Works on both Windows and Linux (at least easily installable) I've looked at Dvorak and Neo, they both have a "shortcut problem", i.e. web-browsing and most frequent Emacs combinations use both parts of the keyboard. Using right Ctrl is usually not an option, since it'll give me RSI much faster than keeping QWERTY/Z. Funnily enough, mirroring the default Neo layout would probably be enough for me. So, any ideas?

• Homemaking a 2d soft body physics engine

  - by Griffin

  hey so I've decided to Code my own 2D soft-body physics engine in C++ since apparently none exist and I'm starting only with a general idea/understanding on how physics work and could be simulated: by giving points and connections between points properties such as elasticity, density, mass, shape retention, friction, stickiness, etc. What I want is a starting point: resources and helpful examples/sites that could give me the specifics needed to actually make this such as equations and required physics knowledge. It would be great if anyone out there also would give me their attempts or ideas. finally I was wondering if it was possible to... use the source code of an existing 3D engine such as Bullet and transform it to be 2D based? use the source code of a 2D Rigid body physics engine such as box2d as a starting point?

• DNS slowdowns on development environment

  - by Sequenzia

  I have a local development environment setup on my Mac. I am running an Ubuntu Web Server inside of a Virtual Box VM. I setup a host file on my Mac that points my dev site to the IP of the Ubuntu Virtual Server. Everything works good other than the fact a lot (not all) of the time it takes more than 5 seconds to load a page. I used firebug to track down where the problem is and when it's slow the DNS part of my request is taking over 5 seconds. Like I said it's not all the time. Sometimes it resolves and loads the page within milliseconds. The same page one click will be super fast and then the next time it takes over 5 seconds. It's really slowing me down and I am not sure what is causing it. Anyone have any ideas? Any help would be great. Thank

• Learning c++ by contributing to open source projects

  - by user1189880

  I have some general programming experience with a few different languages, my most skilled being php. I want to spend a lot of time over the next year learning c++ in much more depth and then eventually get to a good enough level to find a job as a junior developer working in c++. I really struggle to find things to develop as toy programs so want to contribute to an open source project in c++ to get really stuck in to. But the projects I see on github in c++ are very large and will require a lot of knowlege to even get started. Are there any smaller projects that I can contribute to or are there any other good ideas for learning c++ from a practical level.
