• How to learn programming for a medium scale project form a beginner? [closed]

  - by Lin Xiangyu

  I study programming by myself.I have learn servel programming languages. but I never write a project more than 1000 lines. I know the best way to improve programming skills is practise. The problem is many books, just talk about the programming language, or talk about build a project from a high level. Fews of books will teach how to build a middle scale project. For example, I want to build a simple HTTP Server(Nor like Apache or just a simple listenr to a port), a Markdown Parser, or a download tools just like emule or wget. I don't know what to do. I may found peaces of code in the web, or found familiar project in the Github. I don't know how to read the code. I want to some tutorial that can told me how to build the project step by step, teacher me how to write thousands lines of code. Any suggest?

• How many SQL Server DBAs does an organization need?

  - by RickHeiges

  "How many SQL Server DBAs do we need?" - This is a question that often comes up in conversations with customers. Essentially, customers want to know if they have enough DBAs or too many. This is not a trivial question. If you do some research online via your favorite search engine, you will most likely come across numbers such as 40-65 DBs per DBA (for SQL Server). I remember finding another number relating to storage space instead of the number of DBs; the range was 3-5TB per DBA. I have had custoemrs...(read more)

• Whats after the iPAD?? check out the new Augmented Reality Glasses

  - by Stephen Slade

  Everyone loves their new iPad! The rich features, portability, plethora of apps and ease of use make this the new clipboard on the factory floor or electronic notebook for meetings. But how many business people walk into an hours meeting and really start typing notes on their PC?..yes some do, but for the general business public there are new technologies coming down the road. The iPad is the latest holla-hoop; and the next gen device I feel is the Augmented Reality Glasses. Your glasses will be your screen, have an earpiece, be wireless enabled, your smart watch be your electronics and maybe your belt can be an extended battery pack.  I'm anxious to test one of these. The TELEGRAPH writes:  "Android software is believed to power the gadget, enabling similar features to its smartphone and tablets. A 3G /4G data connection, motion sensors and GPS navigation are believed to be included in the device's capabilities. The augmented-reality glasses are the culmination of a two-year initiative called Project Glass, developed in the clandestine Google X lab, ..in Mountain View, ...The New York Times suggested they could cost between $250-$500 " http://www.telegraph.co.uk/technology/news/9187547/Google-unveils-augmented-reality-glasses.html

• How do I get security updates for restricted/partner packages?

  - by laramichaels

  I want to perform just security updates on Ubuntu 12.04 LTS, keeping the rest of the system unchanged. I need to do this from the command line, no the GUI update manager. I have implemented the solution described here, which seems to work great for this purpose. I merely substituted 'precise' for 'lucid' given that I am on 12.04. My question is: by using apt pinning as described in that answer, will I still receive security updates for packages distributed through the "other" repositories - partner, restricted, multiverse, etc? Or will it only get me updates for the packages in the "core" distribution? thanks! ~l

• Valid concerns over shared developer team

  - by alphadogg

  Say your company is committed (and don't want to consider not doing this) to sharing/pooling a development team across a handful of business units. What would you setup as concerns/expectations that must be cleared before doing this? For example: Need agreement between units on how much actual time (FTE) is allocated to each unit Need agreement on scheduling of staff need agreement on request procedure if extra time is required by one party etc... Have you been in a situation like this as a manager of one unit destined to use this? If so, what were problems you experienced? What would you have or did implement? Same if you were the manager of the shared team. Please assume, for discussion, that the people concerned know that you can swap devs in and out on a whim. I don't want to know the disadvantages of this approach; I know them. I want to anticipate issues and know how to mitigate the fallout.

• Why do business analysts and project managers get higher salaries than programmers? [closed]

  - by jpartogi

  We have to admit that programming is much more difficult than creating documentation or even creating Gantt chart and asking progress to programmers. So for us that are naives, knowing that programming is generally more difficult, why do business analysts and project managers get higher salary than programmers? What is it that makes their job a high paying job when even at most times programmers are the ones that go home late? UPDATE Excuse my ignorance, from some of the response it seems that the reason why BAs and PMs gets higher salary because they are the ones that usually responsible for the mess programmers make. But at the end of the day, it is programmers that get their hands dirty to fix the mess and work harder. So it still does not make sense.

• Unit and Integration testing: How can it become a reflex

  - by LordOfThePigs

  All the programmers in my team are familiar with unit testing and integration testing. We have all worked with it. We have all written tests with it. Some of us even have felt an improved sense of trust in his/her own code. However, for some reason, writing unit/integration tests has not become a reflex for any of the members of the team. None of us actually feel bad when not writing unit tests at the same time as the actual code. As a result, our codebase is mostly uncovered by unit tests, and projects enter production untested. The problem with that, of course is that once your projects are in production and are already working well, it is virtually impossible to obtain time and/or budget to add unit/integration testing. The members of my team and myself are already familiar with the value of unit testing (1, 2) but it doesn't seem to help bringing unit testing into our natural workflow. In my experience making unit tests and/or a target coverage mandatory just results in poor quality tests and slows down team members simply because there is no self-generated motivation to produce these tests. Also as soon as pressure eases, unit tests are not written any more. My question is the following: Is there any methods that you have experimented with that helps build a dynamic/momentum inside the team, leading to people naturally wanting to create and maintain those tests?

• Delta-update Firefox Aurora package from PPA

  - by ignite

  I am using Firefox Aurora in my Ubuntu 12.04 which I have installed via its ppa (ppa:ubuntu-mozilla-daily/firefox-aurora). As expected of Aurora, I get an update usually after 2-3 days. I have Firefox Aurora installed in Windows too. There also I get updates in 2-3 days but size of update is usually 4-5 MB, while in Ubuntu it's always around 20 MB. What is the reason for this difference? Is there any way by which I can download and install only the changes and not the entire Aurora again and again?

• How to setup a user account for a web application

  - by ximus

  Hi, What are the main guidelines to setting up a user account on a Linux machine for a web app? In my case it is a Rails application that does file management. First thing I can think of is to limit access rights to only the directories it needs. But how exactly should I go about this? Setup rights through a user group or a through the user's ownership of those directories. I have very little experience in user rights management. What else do I need to consider? I've heard of ACL's and SELinux, do I need to look into any of these to guaranty decent security for my simple web app? Any advice about this and anything not mentioned welcomed, Thanks, Max. I will be using Ubuntu.

• Retain only dependencies of a given package

  - by Karthik

  I am trying to have a minimal version of Ubuntu, having only those packages necessary to run mininet. So, I would like a solution, where I would be able to uninstall all the packages from the system, except those that are needed to run mininet. A much more preferable solution would be to be able to create a new ISO, with mininet and all it's dependencies. Is there any program out there which is already capable of this? If not please guide me on how I can solve my problem? Note: I need to retain not only the direct dependencies of mininet, but also dependencies of dependencies and so on. The final system should be able to run mininet without a hitch.

• Is a company order to switch to a certain IDE a red flag?

  - by Justin Alexander

  I recently joined a rapidly growing startup. In the past 3 months the development team has grown from 4 to 12. Until now they were very laissez-faire about what developers used to do their work. In fact one of the things I initially found attractive about the company is that most programmers used Linux, or whatever OS they felt best suited their efforts. Now orders, without discussion, have come down that everyone is to switch to Eclipse. A fine editor. I prefer SublimeText2, but it's just my personal taste. Is this a red flag? It seems capricious and unreasonably controlling to tell developers (non-MS) what IDE or tool-sets to use if they are already settled in and productive.

• Hard-copy approaches to time tracking

  - by STW

  I have a problem: I suck at tracking time-on-task for specific feature/defects/etc while coding them. I tend to jump between tasks a fair bit (partly due to the inherit juggling required by professional software development, partly due to my personal tendancy to focus on the code itself and not the business process around code). My personal preference is for a hard-copy system. Even with gabillions of pixels of real-estate on-screen I find it terribly distracting to keep a tracking window convienient; either I forget about it or it gets in my ways. So, looking for suggestions on time-tracking. My only requirement is a simple system to track start/stop times per task. I've considered going as far as buying a time-clock and giving each ticket a dedicated time-card. When I start working on it, punch-in; when done working, punch-out.

• Personal knowledge base [closed]

  - by AlexLocust

  Possible Duplicate: How do you manage your knowledge base? Hello. Now I am using easy writing pad for scratches while doing some researches, solving troubles or doing workarounds. But.. you now, it's really difficult to remember all details of founded solution and it's alternatives after few months. And writing pad is not wery useful. Usually writing pad doesn't contains half of needed inforation: links founded in internet, output of some test commands and etc. Now I'am looking for a tool for storing information about my researches and it's results. Basic reqirements: ability to store files; ability to store formatted text (kind of HTML will be nice) with hyperlinks and code snippets; tags on notes; easy to use. Now I'am thinking about some kind of file-system organized storage, but I think it will be inconvenient. Another thinks is local wiki or blog. So, my question is: How do you organize you knowlege base? What tools do you use, and what "pros and cons".

• The Written Roles of Chief Technology Officer

  - by Jon Hopkins

  A follow up to this question: The Written Roles of Software Development Manager What is the role and what are the responsibilities of a CTO when it's done well, with particular reference to how it might pertain to a programmer with aspirations towards this sort of position? (Reason for asking - it's one potential career destination for programmers looking to move away from a purely hands-on role and for those with this sort of ambition it's worth knowing what it actually entails).

I found the following similar question : Errors while updating Ubuntu 11.10 , But the solutions mentioned ( changing the download server, running apt-get clean, apt-get autoclean) and have also tried removing the /var/cache/apt/archives/lists direcotry. As a result of this, I am unable to install any new packages.

• Why can't I refresh the list of packages?

  - by Elysium

  This might be a duplicate, but I can't find a solution in other posts. Whenever I try to update I get this message: ERROR###ERROR###ERROR###ERROR###ERROR###ERROR###ERROR E:Encountered a section with no Package: header, E:Problem with MergeList /var/lib/apt/listspackages.medibuntu.org_dists_quantal_free_i18n_Translation-en, E:The package lists or status file could not be parsed or opened. I have tried runnig this in the terminal: sudo rm /var/lib/apt/lists/* -vf sudo apt-get update It doesn't work at all. I cant even open the software sources and "sudo apt-get check" gives me this message: Reading package lists... Error!

UPDATE: solution for me was to remove the medibuntu-keyring through synaptic manager and removed mediubuntu from the software sources too manually. This seems to have solved the problem. The update manager doesnt give me any error messages anymore.

• Tool to search for packages whose installed version does not match any version from a repository?

  - by Ryan Thompson

  I just upgraded from Lucid to Maverick, and as expected, all my PPAs were disabled. I have re-enabled most of the ones that I want, but I would like to get a list of all packages that I installed from PPAs that I no longer have enabled. I feel that the best way to do this would be to search for all packages where the currently installed version of that package does not match any version from a currently-enabled repository. Is there an easy way to search for such packages. Command-line solutions welcome.

• Does Ubuntu Touch consume less than Android?

  - by Eduard Florinescu

  One of the problems of new OSs is power consumption. That is because power and performance requires a lot of tweaks and experience with the kernel, drivers and OS code-base on one hand, and a lot of extensive long-term test and quality assurance on the other hand. Given that Android is a rather old and established OS I saw that it has pretty good power consumption. Phoronix does this kind of comparissions but I was not able to find to much about Ubuntu Touch. Does Ubuntu Touch consume less than Android in general, do you have data on some platforms compared?

For one of my servers, I've chosen a red color to show in the status bar. Let's pretend this is a production server, and I want the red to remind me to use caution.

• What options do individual have to fork a project?

  - by skrco

  Let's assume our example individual has an idea, engagement, ... to fork project. By project I mean any kind of software - thick client, web site, portal, service, driver, plc, ... - anything that can be programmed. Motto of question: What options do our example individual have to fork this project from the early beginning through getting collaborators and users to mature software? Here are the main subquestions: Sandbox phase: Where can he announce his idea and proposal and receive positive/negative critic and feedback? Development phase: Where can he build his team to work on this project? Yet deployed phase: Where can he schedule tasks, assign tickets and bugs to be solved? and the list can go on... What really interests me is the "sandbox phase question".

• Hardware and Software Working Together - What Does LJE say?

  - by Stephen Slade

   IDG News Service - Oracle CEO Larry Ellison said Oracle will continue to bet on selling high-end custom hardware for its software products, even amidst a growing trend toward roomfuls of cheap, generic servers. "You have to be in the hardware business and the software business, to get the best possible system," he said during a keynote speech at Oracle's OpenWorld conference in Tokyo. "We believe it's the right idea, we believe it's the next generation of computing, we believe all the pieces have to fit together." Ellison, as he has often done in the past, repeatedly referred to Apple as his "favorite example" of such tight integration. He was a close friend of Apple's co-founder Steve Jobs and previously served on Apple's board of directors.He said sales of Oracle's advanced servers were booming and generating around a billion dollars a year in revenue for the company, which has until recent years focused almost exclusively on its software offerings. With the explosion of popular online services and the increasing number of mobile devices that access them, demand is high for databases that can quickly respond to high numbers of relatively simple queries. While Oracle is pitching its expensive, finely-tuned machines to meet this requirement, Internet behemoths like Google, Facebook and Microsoft increasingly rely on armies of low-cost, easily replaceable servers. Ellison emphasized the high specifications of Oracle's servers, which come packed with multiple terabytes of RAM and flash-based storage for speed. Such machines are superior to large server farms, he said, because they require far less electricity and floor space, and are also cost competitive. When asked about whether purchasing such products would lock customers in to expensive hardware from Oracle, he promised that the company's software would always run on "multiple hardware sources."  Ellison, who spoke from Kyoto, Japan's ancient capital, was shown live online via webcast. The Oracle founder has a fondness for Japanese architecture and is staying in his large garden residence in the city Source: Ellison: Hardware-software integration key, Apple is best example. Oracle's founder and CEO reaffirmed his commitment to custom hardware for its software products  LINK to Computerworld article Apr 5, 2012 http://www.computerworld.com/s/article/9225858/Ellison_Hardware_software_integration_key_Apple_is_best_example?source=CTWNLE_nlt_entsoft_2012-04-09&utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+computerworld%2Fs%2Ffeed%2Ftopic%2F173+%28Computerworld+Databases+News%29#disqus_thread

Any tips are welcome, e.g. how can I figure out which process is accessing the disk, are there any daemons doing this? I know it isn't a cron job.
