• Is there a title for someone who is both a Software Developer and a Business Analyst?

  - by gyin

  I usually see two job titles in the IT industry. My understanding of their most commonly accepted usage (simplified): Business Analyst: Main role is eliciting the users' needs Software Developer Main role is to design, build and test a software solution answering the needs I'm wondering: "How we should call somebody whose role is to do both of the roles above?" Is this a common job title? And is trying to find people with these broadness of skills realistic, difficult? EDIT: I'm specifically interested to name Lead Software Developers who have eventually learned and can apply techniques of Business Analysis.

• Optimize bootup sequence

  - by ubuntudroid

  I'm on Ubuntu 11.04 (upgraded from 10.10) and suffering really high bootup times. It got so annoying, that I decided to dive into bootchart analysis myself. Therefore I installed bootchart and restarted the system which generated this chart. However, I'm not really experienced in reading such stuff. What causes the long bootup sequence? Edit: Here is the output of hdparm -i /dev/sda: /dev/sda: Model=SAMSUNG HD501LJ, FwRev=CR100-12, SerialNo=S0MUJ1EQ102621 Config={ Fixed } RawCHS=16383/16/63, TrkSize=34902, SectSize=554, ECCbytes=4 BuffType=DualPortCache, BuffSize=16384kB, MaxMultSect=16, MultSect=16 CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=976773168 IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120} PIO modes: pio0 pio1 pio2 pio3 pio4 DMA modes: mdma0 mdma1 mdma2 UDMA modes: udma0 udma1 udma2 udma3 udma4 udma5 *udma6 AdvancedPM=no WriteCache=enabled Drive conforms to: unknown: ATA/ATAPI-3,4,5,6,7 * signifies the current active mode And here the output of hdparm -tT /dev/sda /dev/sda: Timing cached reads: 2410 MB in 2.00 seconds = 1205.26 MB/sec Timing buffered disk reads: 258 MB in 3.02 seconds = 85.50 MB/sec

• Ubuntu server and services

  - by Vicenç Gascó

  I've been using Linux+Plesk Virtual Server as a web server for a while, but I want to give a try on doing it manually, so my question is: I'll have a server which is: 80GB HDD, 4GB RAM, 1TB Bandwith, 1 Dedicated IP. And I use the following things on my Virtual nowadays: Mail server DNS server Apache + PHP 5.5 + MySQL FTP SSH My question is, without Plesk, can I achieve manually all those functionalities -know that I am not a terminal pro-, actually upgrading some of them to look like that with ubuntu server?: Mail server (with a nice webmail included) DNS server nginx + PHP 5.5 + MySQL + MongoDB FTP + SFTP SSH GIT Server Which ubuntu server should I chose? [EDIT] I almost forgot, I'd like to know how much Bandwith and CPU is using each of my webapps (one per domain usually), and the overall (not just from the webapps, but also mail, dns, etc...) ... usually Plesk does that for me, and I don't know how to measure that without it!

• What would be a good way to request comments?

  - by WarpEnterprises

  In the project/team I'm working the frequency of comments is a little low. One reason might be that it is not clear to the long-time devs what lines in the code really needs a comment (each part of the project has quite fixed devs). To increase this we plan to let team members review the code and check in "requests for comments", which the main dev of that part should replace with useful comments. Do you think this could work? If "yes": what tags should we use to mark? (e.g. //TODO please comment) Can you think of alternatives for this process? Edit: I appreciate your answers about best practice in commenting and writing code, and I completey agree. But my question targets the cases where refactoring is not an option (not wanting to change working code, not wanting to "accuse" main dev of producing code that needs refactoring,...) - so only more or better comments are an option (at least for this question).

• does unused vertices in a 3D object affect performance?

  - by Gajet

  For my game I need to generate a mesh dynamically. now I'm wondering does it have a noticeable affect in fps if I allocate more vertices than what I'm actually using or not? and does it matter if I'm using DirectX or OpenGL? edit final output will be a w*h cell grid, but for technical issues it's much more easier for me to allocate (w+1)*(h+1) vertices. sure I'll only use w*h vertices in indexing, and I know there is some memory wasting there, but I want to know if it also affect fps or not? (note that mesh is only generated once in each time you play the game)

• How to log frame times in an existing OpenGL game? [on hold]

  - by J Collins

  I have been using FRAPS for some time to benchmark instantaneous frame rates in an OpenGL game for which I am creating maps. Until recently it had been quite reliable. Now however, the bench marking shortcut has been unresponsive and I can't explain why. Ideally I could have a logging system automatically start logging whenever the game had focus, but can't find a good tool to do so. So option a) find out how to make FRAPS reliable again or b) find a new tool. Could one of you kind folks help me? Edit: Concise questions Is there a widely recognised tool to log frame drawing times and rates for compiled applications? If the answer is universally the FRAPs tool, are there any clear cases in which logging will not or should not be expected to work?

• How safe is ubuntu?

  - by VJo

  Last week I started desktop sharing using krfb. Since I continue last session, this program keep on starting again. Two days ago I noticed messages poping up saying something like "rejecting uninvited connection from (some ip)", but today I figured it might be because of this and I was right. The krfb was running in the background. Hence the question. How safe is ubuntu? Should I expect someone to connect to my computer and erase everything I got on disk? EDIT To extend my question : how safe it is comparing to other OSs (windows, mac,...)? How safe it is comparing to other distros?

• Feedback/bug tracking system for an alpha/beta phase website? [on hold]

  - by randomguy

  I'm developing a website and it's closing onto a private alpha/beta phase. It will be exposed to a small selected group of individuals who will provide a fair amount of feedback. What options do I have for this feedback system? I would certainly like to make it collaborative (excluding email). I could mock up a really simple message board, but would rather use my time elsewhere. The feedback will mainly consist of feature suggestions and bug reports. Edit: Actually, would prefer if it's a free hosted service.

• Hosting my own SVN repositories

  - by TheAdamGaskins

  I've been experimenting with Google Code and Sourceforge and the like, and am happy with what I've found. The main problem with them, is that you have to have your project be open source to use them, so anybody can edit them. So... is there some way I can have my own svn repositories on my own server? I have FTP access, cpanel, and all that. If it helps any: Operating system Linux cPanel Version 11.26.20 Architecture x86_64 MySQL version 5.0.91-community-log Apache version 2.2.13 PHP version 5.2.11 cPanel Pro 1.0 (RC1)

• Alternatives to Google Sites for a personal web site?

  - by Oleg2718281828

  I'd like to find a hosting solution for my personal, fairly low-traffic, web site. I think Google Sites would suit me perfectly, but I've heard horror stories about Google's algorithms shutting down all your accounts on a whim, with no right of appeal, so I'm naturally worried, because I don't want to lose my Gmail. Edit I'm talking about cases like this one: I tried contacting somebody at Google support ("Surely they should have a support department, right?" Nope, wrong!) (The victim managed to regain access to his Gmail account when his case went "viral", but he never got an explanation as to why he had been locked out in the first place) Are there good, preferably free, alternatives to Google Sites and what are their PROs and CONs? One requirement is that I should be able to point the DNS (foobar.com) to it.

• How do I remove the Skype icon from the system panel?

  - by superjudge3

  I have been trying for some time to remove the Skype icon in the upper panel in Ubuntu 11.10, but to no avail. I have went into dconf, went to desktop - unity - panel, and I looked to delete 'Skype' from the whitelist. But Skype isn't in the whitelist! And it's showing up on the panel! Something smells fishy here, and I was wondering if anyone had an answer as to a) how I can actually remove the Skype icon from the gnome panel and b) why an icon still show up there if it isn't in the whitelist? Also, if it's relevant, I use Unity. EDIT: So, the only solution for this issue is the scorched earth strategy of removing sni-qt?

• Is backing up a MySQL database in GIT a good idea?

  - by wobbily_col

  I am trying to improve the backup situation for my application. I have a Django application and MySQL database. I read an article suggesting backing up the database in Git. On the one hand I like it, as it will keep a copy of the data and the code in synch. But GIT is a designed for code, not for data. As such it will be doing a lot of extra work diffing the mysql dump every commit, which is not really necessary. If I compress the file before storing it, will git diff the files? (The dump file is currently 100MB uncompressed, 5.7Mb when bzipped). Edit: the code and database schema definitions are already in GIT, it is really the data I am concerned about backing up now.

• Find out when a new domain appears in search results

  - by TerryB

  Does anyone know a way to perform the following: I want to know whenever a new domain starts appearing in the google search results for a particular query. For a given google search query, I'd like to receive an alert whenever a new domain pops up and starts appearing in the search results for that query. Alternatively, it would be great if you could just sort google search results by the age of the domain, making it easy to find new sites. As far as I can tell you can only sort by when the page was "last updated". Is something like this possible? EDIT: Following John's suggestion of Google Alerts. The problem with Google Alerts is that it sends you any new PAGES appearing in the search results, not just new DOMAINS.

• Is it a good idea for exams to be done on a computer?

  - by vemv

  In some colleges students are let to use an IDE and Internet and in mine you have to write down your solution in paper. As far as I know, it's pretty much impossible to make a correct non-trivial program on the first try. I'd be fine with no using computers if my teachers assessed my approach instead my code -literally-... that's not the case unfortunately. Which ones are more usual, 'written' or 'coded' exams? And which way is the most adequate? Edit - question title changed (it used to be Should students have the right to do exams using a computer?)

• DualBoot 32Win & 64Mac from Live USB +Persistance

  - by josephsmendoza

  So I have a 32 bit Live USB with persistance that I use to write code, cause that's just how I roll. I can boot it onto my school computers(32 bit Win) no problem, but obviously not my Mac (2007 iMac, 64 Bit). Currently I use VMWare Fusion 6 Pro and a Plop Linux image to use the usb at home, but I can only get 900mb of ram for my VM. I was hoping to make a Live USB that can boot 32 bit and 64 bit for mac, with a shared persistance file, this way I can use my computer's full 2GB. Also, I'm not allowed edit any part of this Mac. Do Not reply telling me it's impossible. Please only solutions. Thank you, and have a unicorntastic day!

• Shutdown issues on my Dell XPS M1530

  - by CppLearner

  On my Dell XPS M1530 lapttop, I am facing issues with shut-down option after upgrading to 12.04 LTS from 11.10. Sometimes it shutdowns "cleanly". But other times everything goes down but I can still see the power LED glowing (even after removing the power cord). If I keep it like that laptop temperature increases. So finally I opt for "hard shut-down" (i.e. pressing the power button on). Any thoughts what is happening here?. Edit: I just found this link to already reported bug https://bugs.launchpad.net/ubuntu/+source/linux/+bug/987933

• Switching to an external display, when primary is broken

  - by Shazzner

  I've successfully install Ubuntu 11.10 Desktop (x86) on an old(er) laptop that unfortunately has a broken screen, so there is an external monitor plugged in. On the livecd it come up on the secondary display just fine and I was able to install ubuntu and everything. Unfortunately when I reboot into Ubuntu proper now, the secondary display is off and I'm literally driving blind here trying to switch it to the secondary display. Using Nvidia open source drivers. Things I've tried: Rebooting back into livecd, mounting the partition and trying in vain to find a config file (it uses the open source drivers so no Xorg.conf I could edit manually) Trying to blind-type xrandr settings into what I hope is terminal: xrandr --output VGA1 --auto (nothing happened) Trying to blind install openssh-server so I could ssh into it and maybe configure it from my working computer. For some reason though, no luck. Ubuntu really should default to expanding to all screens for this use case.

• What are the challenges and benefits of writing games with a functional language?

  - by McMuttons

  While I know that functional languages aren't the most commonly used for game writing, there are a lot of benefits associate with them that seem like they would be interesting in any programming context. Especially the ease of parallelization I would think could be very useful as focus is moving toward more and more processors. Also, with F# as a new member of the .NET family, it can be used directly with XNA, for example, which lowers the threshold quite a bit, as opposed to going with LISP, Haskell, Erlang, etc. If anyone has experience writing games with functional code, what has turned out to be the positives and negatives? What was it suited for, what not? Edit: Finding it hard to decide that there's a single good answer for this, so it's probably better suited as a community wiki post.

• Do you actually write 'clean code'?

  - by ykombinator

  I have seen some programmers tweaking their code over and over again not only to make it 'work good', but also to make it 'look good'. IMO, 'clean code' is actually a compliment indicating your code is elegant, perfectly understandable and maintainable. And the difference comes out when you have to choose between an aesthetically appealing code vs. code that's stressful to look at. So, how many of you actually write 'clean code'? Is it a good practice? What are the other benefits or drawbacks of this? EDIT: I came across the term 'girl-code' here.

• How do I get a Vodafone K3772-Z USB modem working?

  - by Ian

  I recently switched from Win 7 to Ubuntu 12.04...Best day of my life :) I have a question relating to my Vodafone K3772-Z USB modem. When I plug it in, the lights start flashing on the device, meaning that it is functional. In the network menu I get a "Wired network Vodafone K3772-Z disconnected". I have set up the a connection by using Edit connections - mobile broadband - Add, but in the add window the "Create a connection for this mobile device" is blanked out and says "Any Device". Does anyone perhaps have an idea of what I could do to get it working?

• Need help migrating from Wubi

  - by neilh

  I know this question has been asked, but I am looking for specific help with my partition selection. I want to migrate my install from wubi to be a dual boot. When I installed it I choose a small, partition, around 30GB. I am following these instructions: https://help.ubuntu.com/community/MigrateWubi I see sda4 matches that size, but has mount point as '/host', am I okay to use this one? EDIT: Here is a screenshot of my partitions. http://i.imgur.com/ozPe0.png My windows partition is actually not there, that is down as sdb1, so safely out of the way? I can confirm sda4 is the location of the 'virtual partition' and is an otherwise, unused 26GB partition. It's also where I would like to migrate to a full install to.
