• Is it possible to skip an LTS upgrade?

  - by Jo-Erlend Schinstad

  If you want to upgrade from 10.10 to 12.04, then you'll need to follow the upgrade path; 10.10 11.04 11.10 12.04. However, with LTS versions, you can upgrade directly, so that you can upgrade from 10.04LTS to 12.04LTS directly. But now, LTS versions are supported for five years while there's still a new LTS every two years. That means you can choose to skip an LTS. So the question is; will I be able to upgrade from 12.04LTS to 16.04LTS directly, or will I then have to follow the LTS upgrade path; 12.04 14.04 16.04?

• Leading an offshore team

  - by Chuck Conway

  I'm in a position where I am leading two teams of 4. Both teams are located in India. I am on the west coast of the U.S. I'm finding leading remote teams challenging: First, their command of the English language is weak. Second, I'm having difficultly understanding them through their accents. Third is timing, we are 12 hours apart. We use Skype to communicate. I have a month to get the project done. We've burned through a week just setting up the environments. At this point I'm considering working their hours, 11p PDT to 7a PDT, to get them up to speed, so that I can get the project off the ground. A 12 hour lag time is too much. I'm looking for steps I can take to be successful at leading an offshore team. Update The offshore team's primary task is coding, of course, most coding tasks do involve some design work. The offshore team's are composed of one lead, 2 mid level (4 to 5 years) developers and a junior (~2 years) developer. The project is classic waterfall. We've handed the offshore team a business and a technical design document. We are trying to manage the offshore in an agile way. We have daily conference calls with them and I'm requiring the teams to send me a daily scrum in the form of an email answering the following questions: What did I do today? What am I going to do tomorrow? What do I need from Chuck so I can do my job tomorrow? There is some ambiguity in the tasks. The intent was to give them enough direction for them to develop the task with out writing the code for them. I don't have a travel budget. I am using Fogbugz to track the tasks. Each task has been entered into Fogbugz and given a priority. Each team member has access to FogBugz and can choose what task they wish to complete. Related question: What can we do to improve the way outsourcing/offshoring works? Update 2 I've decided that I can not talk to the team once a day. I must work with them. Starting tonight I've started working the same hours they are. This makes me available to them when they have questions. It also allows me to gain their trust and respect.

• Fix Package is in a very bad inconsistent state

  - by Benjamin Piller

  I can't update my system because it freezes while installing a third-party update (zramswap-enabler)!! Sometimes I get the following message in Update manager: Could not initialize the package information An unresolvable problem occurred while initializing the package information. Please report this bug against the 'update-manager' package and include the following error message: E:The package zramswap-enabler needs to be reinstalled, but I can't find an archive for it. I tried to remove the zramswap-enabler, but it's impossible because I get the following message: dpkg: error processing zramswap-enabler (--remove): Package is in a very bad inconsistent state - you should reinstall it before attempting a removal. Errors were encountered while processing: zramswap-enabler E: Sub-process /usr/bin/dpkg returned an error code (1) Actually i would really reinstall that package, but it is unable to do it! If i remove this third-party PPA then the system is warning me about a very very serious problem. So why can i not install/reinstall/remove/update this package and why freezes the updater if i try to update? -S O L U T I O N-: Okay! Finally i found the solution for this Problem! Step 1. Make sure that your PPA is correctly Step 2. Remove the broken package via the following command: sudo dpkg --remove --force-remove-reinstreq zramswap-enabler Step 3. install the package again (sudo apt-get install zramswap-enabler) Step 4. After restart (not necessary) you are able to install the updates correctly! Actually you can fix any "Package is in a very bad inconsistent state” Issues with this solution!!!

• Requirements/issue tracker similar to online spreadsheet

  - by Maxim Eliseev

  Is there a requirements/issue tracker software which is similar to Google spreadsheet? We have Fogbugz but I find it more heavyweight and slow than a simple spreadsheet. Is there a Fogbugz alternative which is - fast - can show issues/requirements as a spreadsheet (at) and allows in-place editing - supports tree structures (where issue can have child issues)? It is required for a small project. There will be 2 developers and 1-2 other users. I guess that only one user will be actively maintaining it. UPDATE I do not say that a spreadsheet is better than Fogbugz or similar tools. In fact I am looking for a tool which is similar to Fogbugz and could replace a spreadsheet, but faster than Fogbugz and has an additional feature (table-like mode). I'd like to find a tool which can operate in a mode which looks like a table (one row per issue) but has a rich set features (similar to Fogbugs and JIRA). I find Fogbugz (and similar tools) inconvenient because I must enter the web form in order to edit anything. In-place editing (when issues are shown as a table) would be much faster.

• Resources on how to relate structured and semi- / un-structured information

  - by Fritz Meissner

  I don't have a great background in information organisation / retrieval, but I know of a few ways of dealing with the problem. For structured information, it's possible to go OOish - everything "has-a" or "has-many" something else, and you navigate the graph to find relationships between things. For unstructured information, you have techniques like text search and tagging. What resources - articles or books - are there that summarise the CS theory behind these techniques or could introduce me to others? I'm developing a system that needs to handle capture and retrieval of information that ranges from necessarily unstructured (advice about X) to structured (list of Xs that relate to Ys) to a combination (Ys that relate to the advice about X) and I'd like to get some insight into how to do it properly.

• How can I avoid team burnout?

  - by Shawn Dalma

  I work for a small web company that deals with a lot of projects, a few at any given time are development heavy for us (400-1500 hours or more) and I've been noticing developers get extremely burnt out on a project after 150 hours or so. I've been toying around with the idea of working some form of rotation/rest so when someone reaches the threshold, they at least get some time off of working on that project. Is there an industry standard approach?

• Intelligence as a vector quantity

  - by Senthil Kumaran

  I am reading this wonderful book called "Coders at Work: Reflections on the Craft of Programming" by Peter Seibel and I am at part wherein the conversation is with Joshua Bloch and I found this answer which is an important point for a programmer. The paragraph, goes something like this. There's this problem, which is, programming is so much of an intellectual meritocracy and often these people are the smartest people in the organization; therefore they figure they should be allowed to make all the decisions. But merely the fact they are the smartest people in the organization does not mean that they should be making all the decisions, because intelligence is not a scalar quantity; it's a vector quantity. Here at the last sentence, I fail to get the insight which is he trying to share. Can someone explain it in a little further as what he means by a vector quantity, possibly trying to present the same insight. Further down, I get the point that he is not taking about having an organization where non-technical people (sometimes clueless) can be managers of the technical people for some reason that they can spend more time to write emails well, because the very next statement following the above paragraph was. And if you lack empathy or emotional intelligence, then you shouldn't be designing APIs or GUIs or languages. I understand that he is saying that in Software engineering, programmers should know how the users will see their product and design for them. I felt the above paragraph was very interesting.

• How to determine number of resources to be allocated in a software project

  - by aditi

  Last day I have been interviewed and the interviwer asked me as given the outline of a project, how can we determine the number of resources to be needed for the same? I donot know to do do so? Is there any standard way of doing so? or is it based on the experience? or how.... I am pretty new in this activity and my knowledge is zero at present .... so any clear explanation with some example(simple) will help me(and people like me) to understand this. Thanks

• APT wedged by kernel version mismatch

  - by Leopd

  Apt is seemingly unable to do anything useful for me, repeatedly giving messages of this form: dpkg: dependency problems prevent configuration of linux-server: linux-server depends on linux-image-server (= 3.2.0.37.44); however: Version of linux-image-server on system is 3.2.0.37.45. linux-server depends on linux-headers-server (= 3.2.0.37.44); however: Version of linux-headers-server on system is 3.2.0.37.45. dpkg: error processing linux-server (--configure): dependency problems - leaving unconfigured This is basically the same problem as I cannot install any package (linux-image-server, linux-server dependencies errors) which got closed Duplicate to an answer that is totally useless for this situation. None of the advice in that very generic answer about dependencies helps. Explicitly: sudo apt-get clean sudo apt-get autoclean sudo apt-get update all have no not effect. While sudo apt-get -f install sudo dpkg --configure -a sudo apt-get -u dist-upgrade sudo apt-get -o Debug::pkgProblemResolver=yes dist-upgrade all give some form of the error message above.

• Is there a constant for "end of time"?

  - by Nick Rosencrantz

  For some systems, the time value 9999-12-31 is used as the "end of time" as the end of the time that the computer can calculate. But what if it changes? Wouldn't it be better to define this time as a builtin variable? In C and other programming languages there usually is a variable such as MAX_INT or similar to get the largest value an integer could have. Why is there not a similar function for MAX_TIME i.e. set the variable to the "end of time" which for many systems usually is 9999-12-31. To avoid the problem of hardcoding to a wrong year (9999) could these systems introduce a variable for the "end of time"?

• winusb formatting and installation error, lost data storage on 32gb flash drive

  - by Cary Felton

  i recently purchased a pny brand 32gb usb drive to use for configuring a dual boot on my computer, and for hdd files backup. i also recently installed zorin os 6.1 as my main os, and then downloaded winusb for linux, and set it to install the iso for windows 8 release preview as the activation code is still good untill jan.2013, and there was an error on the installation. i rebooted the computer, plugged in the usb drive, and i went from 32gb usable space to somehow having a partitioned drive (mounted as two separate drives) one being 3.7gb, and the other being i believe 25gb or so... i then formatted the drive with gparted back to fat32, and it still read as a windows usb with the installation files on it still? so then i took my usb drive to my library which runs windows 8, i installed bootice, and completely reformatted my usb drive, and somehow it is usable, but still not perfect. it reads i only have 29.9gb usable space... i have already thought of the non usable area, and that doesnt account for this error as when i first bought the drive and plugged it in on linux, it read total drive space was 32.2 and exactly 32 was usable. somehow i am short by 2gb of space which is very critical for what i am doing. i love linux, i only needed windows for bluray playback with daplayer as it wont work well in wine, but if i keep losing space on my usb drives im afraid ill have to switch back. any help would be appreciated as i already visited pny's site, and they have no support for this issue, and im not that fond of partitions, file systems, or formatting.

• Displaying google analytics data on my website

  - by anon-user0

  I sale adspace for my websites directly to the advertisers. I ad page where I want to show google anaylytics information that update automatically without me having to manually update everyday or every month. Something like this: http://wstats.net/en/website/riverplate.com#stat_trafic I don't want to use embedded or iframed third party services. I know google has public API and you can connect it to google graph API to to show pretty graphs. There is a tutorial by google here on how to do it: https://developers.google.com/analytics/resources/articles/gdataAnalyticsCharts Few problems: I don't know much javascript The javascript seems to prompt for authntication as opposed to login automatically. (from my understanding by reading comments on the code) Does anyone know of any ready made script that does what I am looking for or know how I can fix this code that will allow me to display analytic info without authenticating? Thanks.

• How do developer get rid of silly requirements?

  - by sugar

  Hmm ! First of all let me give you the note of the requirement. So that you can have idea what kind of problem I am facing. Words From Project Manager : Hey ! Sugar, I am assigning you a task for developing a framework. This framework is supposed to be developed for all iOS application. Please go through brief of the required framework. It should be able to detect the thickness of my Thumb. It should be able to detect whether User is using thumb or Fingers If user is using thumbs/Fingers, Framework should calculate the size of thumb/fingers. Once size is been calculated, all elements of user interface should arranged & resized automatically. ( not specified how & where as its framework - it should be smart enough to arrange automatically ) If thumb size is larger elements should get arranged near by center area of iPad/iPhone If thumb size is smaller elements should get arranged near by corners of iPad/iPhone If thumb size is larger, fonts of all elements should get smaller. ( assuming = aged person ) If thumb size is smaller, fonts of all elements should get larger. ( assuming smaller thumb = low aged person ) Summary : This framework is required for creating user-friendly user-interfaces programmatically. We need to develop a very developer-friendly framework. Framework should be developed in such a way that we can use in as many projects as needed. Well, I am a developer. What I want to have as an answer is as follows. How to describe them - the way of they thinking is bit ridiculous ? How do I explain them - we can better concentrate on developing actual projects ? How do I convince them - that this kind of things even if possible, is not recommended to develop such things ? How do I say politely, gently & respectfully NO to this ? What should I say, So that they can not point at my experience ? ( e.g. you are 3 years experienced guy & you must have abilities to develop such things ) Feeling horror. Please help. Thanks in advance, Sugar. Note : Please help me to tag this question properly. I am stuck & this is real situation. Frustrated & tensed. You guys might have faced such requirements from TopLevel. requesting you to help with your experience. Well ! I came to know that - those TOPLEVEL guys don't have any idea of iPad, iPhone, Apple etc. I would do one thing. Sir, before we go further for framework development. It is strongly recommended to read Apple Human Interface Guidlines.

• Takeaways From CSO Roundtable New York

  - by Naresh Persaud

  Thanks to everyone who attended the Chief Security Officer Roundtable in New York last week. We were lucky to have Dennis Brixus, CSO of McGraw-Hill  as a guest speaker. In addition, Jeff Henley, provided a board level perspective on security. Amit Jasuja discussed Oracle's security formula.  A few takeaways from Jeff's talk that were interesting: Security is a board level issue. The challenge at the board level is that boards have short attention span. The CSO needs to be vigilant in educating the board on the strategic importance of security. Every CSO needs to think about cost. The CSO has to look at the economics of security and demonstrate fiduciary responsibility. We have to think of security as a business enabler. Security is the enabler that helps us expand into new markets and connect better with our customers and partners. While the CSO can't prevent every threat, we have to expect the CSO to have a plan.

• Downgrade a bunch of packages

  - by Manuel

  Maybe you have installed packages from a PPA or an external source (e.g. downloaded a .deb for a package that is available through the Ubuntu repos.). Then you decide to drop these upgraded versions in favour to the official repositories.First step is to remove the entries of the sources.list. Is there a way to downgrade all to the highest available version? I know you can install specific versions with apt-get install [package]=[version] But can you downgrade all?

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

  - 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 are generally more difficult, why does business analysts and project managers gets higher salary than programmers? What is it that makes their job a high paying job when even at most time programmers are the ones that goes home late?

• 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".

• 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?

I will inherit 3 programmers who developed the company web site and do general IT programming. I have the grey hair and credentials to have their initial respect but I'm an engineer, not a manager. I'm looking for practical advise - particularly for the first 90 days - on how to establish myself, keep the team together, and move forward.

• Recommendations for managing DNS issues when hosting customer sites.

  - by Thomas

  I'm working at a company which primarily provides SaaS products but also will host some of our customers corporate websites. My question relates to recommendations for managing DNS for client's domain names. My objectives: Not restrict my ability to change the server's IP address such as might happen when I move my servers to a new host. Not have to contact the customer to change their domain's DNS if I need to change the server's IP address. Often times, customers lose this information or have to track down the one person with any knowledge of the domain settings. Map both .clientdomain.com and www.clientdomain.com to the proper IIS site. However, I'm running into a couple of common problems: Sometimes, the DNS console provided by the client's hosting company does not allow for CNAME records. Sometimes, the DNS console provided by the client's hosting company will not let me create a CNAME entry for .spiffydomain.com because the given hosting company has created a SOA record for that entry or simply requires that .spiffydomain.com be an A record. I believe one solution to #2 is to use a wildcard for a CNAME entry (i.e. *.spiffydomain.com). Is that correct? How do other folks that are hosting many customer's site manage change of DNS entries on their servers?

• How can we plan projects realistically while accounting for support issues?

  - by Thomas Clayson

  We're having a problem at work: we're trying to schedule work so that we can assess time scales and get deadline dates. The problem is that it's difficult to plan for a project without knowing everything that's going to happen. For instance, right now we've planned all our projects through the start of December, however in that time we will have various in house and external meetings, teleconferences and extra work. It's all well and good to say that a project will take three weeks, but if there is a week's worth of interruption in that time then the date of completion will be pushed back a week. The problem is 3 fold: When we schedule projects the time scales are taken literally. If we estimate three weeks, the deadline is set for three week's time, the client is told, and there is no room for extension. Interim work and such means that we lose productive time working on the project. Sometimes clients don't have the time that we need to take to do the work, so they'll sometimes come to us and say they need a project done by the end of the month even when we think that the work will take two months - not to mention we already have work to be doing. We have a Gantt chart which we are trying to fill in with all the projects we have and we fill in timesheets, but they're not compared to the Gantt chart at all. This makes it difficult to say "Well, we scheduled 3 weeks for this project, but we've lost a week here so the deadline has to move back a week." It's also not professional to keep missing deadlines we've communicated to the client. How do other people deal with this type of situation? How do you manage the planning of projects? How much "extra" time do you schedule into a project to account for non-project work that occurs during a project? How do you deal with support issues and bugs and stuff? Things you can't account for during planning? UPDATE Lots of good answers thank you.
