• Can an agile shop every really score 12 on the Joel Test? [closed]

  - by Simon

  Possible Duplicate: Can an agile shop every really score 12 on the Joel Test? I really like the Joel test, use it myself, and encourage my staff and interviewees to consider it carefully. However I don't think I can ever score more than 9 because a few points seem to contradict the Agile Manifesto, XP and TDD, which are the bedrocks of my world. Specifically the questions about schedule, specs, testers and quiet working conditions run counter to what we are trying to create and the values that we have adopted in being genuinely agile. So my question is whether it is possible for a true Agile shop to score 12? [Note: I had this question closed on meta so I have re-posted here]

• kill SIGABRT does not generate core file from daemon started from crontab. [closed]

  - by Guma

  I am running CentOS 5.5 and working on server application that sometimes I need to force core dump so I can see what is going on. If I start my server from shell and send kill SIGABRT, core file is created. If I start same program from crontab and than I send same signal to it server is "killed" but not core file is generated. Does any one know why is that and what need to be added to my code or changed in system settings to allow core file generation? Just a side note I have ulimit set to unlimited in /etc/profile I have set kernel.core_uses_pid = 1 kernel.core_pattern=/var/cores/%h-%e-%p.core in /etc/sysctl.conf Also my server app was added to crontab under same login id as I am running it from shell. Any help greatly appreciated

• The perils of double-dash comments [T-SQL]

  - by jamiet

  I was checking my Twitter feed on my way in to work this morning and was alerted to an interesting blog post by Valentino Vranken that highlights a problem regarding the OLE DB Source in SSIS. In short, using double-dash comments in SQL statements within the OLE DB Source can cause unexpected results. It really is quite an important read if you’re developing SSIS packages so head over to SSIS OLE DB Source, Parameters And Comments: A Dangerous Mix! and be educated. Note that the problem is solved in SSIS2012 and Valentino explains exactly why. If reading Valentino’s post has switched your brain into “learn mode” perhaps also check out my post SSIS: SELECT *... or select from a dropdown in an OLE DB Source component? which highlights another issue to be aware of when using the OLE DB Source. As I was reading Valentino’s post I was reminded of a slidedeck by Chris Adkin entitled T-SQL Coding Guidelines where he recommends never using double-dash comments: That’s good advice! @Jamiet

• System Wide Performance Sanity Check Procedures

  - by user702295

  Do you need to boost your overall implementation performance? Do you need a direction to pinpoint possible performance opportunities? Are you looking for a general performance guide? Try MOS note 69565.1.  This paper describes a holistic methodology that defines a systematic approach to resolve complex Application performance problems.  It has been successfully used on many critical accounts.  The 'end-to-end' tuning approach encompasses the client, network and database and has proven far more effective than isolated tuning exercises.  It has been used to define and measure targets to ensure success.  Even though it was checked for relevance on 13-Oct-2008, the procedure is still very valuable. Regards!

• How To Delete, Move, or Rename Locked Files in Windows

  - by Chris Hoffman

  Windows won’t allow you to modify files that open programs have locked. if you try to delete a file and see a message that it’s open in a program, you’ll have to unlock the file (or close the program). In some cases, it may not be clear which program has locked a file – or a background process may have locked a file and not terminated correctly. You must unlock the stubborn file or folder to modify it. Note: Unlocking certain files and deleting them may cause problems with open programs. Don’t unlock and delete files that should remain locked, including Windows system files.

• Can the Clojure set and maps syntax be added to other Lisp dialects?

  - by Cedric Martin

  In addition to create list using parentheses, Clojure allows to create vectors using [ ], maps using { } and sets using #{ }. Lisp is always said to be a very extensible language in which you can easily create DSLs etc. But is Lisp so extensible that you can take any Lisp dialect and relatively easily add support for Clojure's vectors, maps and sets (which are all functions in Clojure)? I'm not necessarily asking about cons or similar actually working on these functions: what I'd like to know is if the other could be modified so that the source code would look like Clojure's source code (that is: using matching [ ], { } and #{ } in addition to ( )). Note that if it cannot be done this is not a criticism of Lisp: what I'd like to know is, technically, what should be done or what cannot be done if one were to add such a thing.

• How can I remove the Unity Launcher?

  - by Magnus Hoff

  I'm running Ubuntu Netbook. With the recent upgrade to 10.10 I was excited about the Application Menu/the global menu bar and its implications for screen real estate. Unfortunately, the Unity Launcher on the left hand side of the screen takes more valuable space away than the new menu bar gives. Is there any way to get rid of the Launcher? Alternatives I would be satisfied with include: Not having the Launcher at all Having the Launcher hide automatically Having applications open on top of the Launcher (not next to it) (edit:) Note that I am specifically looking for a way to keep the global menubar, while getting rid of the Launcher.

• No root file system - Alternate CD + LVM

  - by Carlos

  I am trying to install 11.10 as dual boot with Windows 7. I have all partitioned well as you can see here: http://www.flickr.com/photos/42897978@N00/7111180385/ I burned the Alternate CD ISO to a CD. Boot from it and followed instructions to Partitioning. There, I configured the LVM partitions as follows: Volume Group ubuntu-vg - Uses Physical Volume /dev/sda7 380GB - Provides Logical Volume home-lv 60GB - Provides Logical Volume root-lv 60GB - Provides Logical Volume swap-lv 6GB That is all I want (note that my /boot is outside of LVM) Then when I say that all is Ok and to write it to disk and continue with the installation, I get the following error. !! Partition Disks No root file system No root file system is defined Please correct this from the partitioning menu. What should I fix and how? I tried issuing the "Revert changes to partitions", but nothing happens. It seems that the LVM configuration has already been written to the CD. HELP!!

• Significance and role of Node.js in Web development

  - by Pankaj Upadhyay

  I have read that Node.js is a server-side javascript enviroment. This has put few thought and tinkers in my mind. Can we develop a complete data-drivent web application utilizing just JavaScript (along with node.js), HTML5 and CSS? Do we still need to use some server-side scripting language (e.g. C#, PHP)? In case we still need to use other scripting languages, what is node.js worth for, or useful? NOTE: Pardon with my knowledge about node.js.

• What naming anti-patterns exist?

  - by Billy ONeal

  There are some names, where if you find yourself reaching for those names, you know you've already messed something up. For example: XxxManager This is bad because a class should describe what the class does. If the most specific word you can come up with for what the class does is "manage," then the class is too big. What other naming anti-patterns exist? EDIT: To clarify, I'm not asking "what names are bad" -- that question is entirely subjective and there's no way to answer it. I'm asking, "what names indicate overall design problems with the system." That is, if you find yourself wanting to call a component Xyz, that probably indicates the component is ill concieved. Also note here that there are exceptions to every rule -- I'm just looking for warning flags for when I really need to stop and rethink a design.

• What Master degree should a programmer have after "ITC"? [closed]

  - by Saleh Feek

  I am sorry if the question is simple. I studied ITC - Information Technology and Computing program, in an Arab university called "Arab Open University". This university actually takes the courses from the Open University in the UK (through a partnership). (Note: some of the courses in the list are different from what I took due to replacement/updating for materials) .......... I am interested in programming in general. It is the same question but in different ways: What is the master degree that is related to a programmer? Generally for someone like me, what is the required/suggested Master degree? For any suggested Master degree please type the formal name for the master degree, so that I can search for it.

• How to elevate engineering culture at large corporations?

  - by davidk01

  One thing I have realized working at a large corporation is that it doesn't matter how smart you are because if everyone else doesn't see the value in what you are doing then you are not going to get very far. It's much harder to convince 1000 people that a certain part of the software stack should be in groovy than it is to convince 10 people of the same thing. I'm curious how people go about elevating the engineering culture at large corporations because I've been running into walls left and right and I would like to be more proactive about how I go about it. I have been advocating tech talks and tech demos along with code reviews as potential solutions. Do people have other suggestions? Note that 1000 people and groovy are just representative examples. I am not married to groovy or any other language and 1000 people is meant to indicate large scale and how to go about teaching a large group of people about best practices and engineering principles in general.

• Juju bootstrap fails with "Temporary failure in name resolution" using Amazon AWS

  - by Will

  I have followed the instructions over at https://juju.ubuntu.com/docs/config-aws.html to try and setup myself with a juju environment. It all seemed to setup alright. SSH keys, Gererate config, repository, adding access id and secret keys to environments.yaml file. Although my key file from aws IAM management console was called credentials.csv rather than rootkey, I couldn't find that link described in the documentation. When I give the command juju bootstrap in the testing page. It fails giving me the error: juju bootstrap ERROR Get https://s3-us-west-1.amazonaws.com/juju-gobblygookmynukmbersinhere/provider-state: lookup s3-us-west-1.amazonaws.com: Temporary failure in name resolution (note I just replaced my numbers for this posting my actual terminal has my numbers in. This is my first attempt at any ec2 work so I have gone in and created new IAM profiles. What have I done wrong? Any help would be great. I think I'm in over my head!

• Prevent nautilus showing partition mounted in bash script

  - by bcbc

  In my bash script I mount partitions, check them, copy files to them, and unmount. When the script mounts the partition, Nautilus pops up with a Window showing the partition and stealing focus. This is something I want to avoid. Note: I know I can change the behaviour of this in System settings, Details, Removable media, Never prompt or start programs on media insertion, but I don't want to change the behaviour e.g. if a USB stick is plugged in, I just want to prevent it in my bash script. Actually this auto display doesn't seem consistent. If I do the exact same command from the terminal, Nautilus doesn't show, and I know there are other mounts in my script that don't show. So what could be causing this? Here's an example of the code: mkdir -p $target/home mount $target/home $homedev Thanks in advance

• detecting when you are going to reach your hit limit for Google Analytics free account

  - by crmpicco

  I am a user of a free Google Analytics account and i'm slightly concerned that I may be approaching the 10,000,000 hit (Pageviews, Events etc) per month. Google state in their documentation: These limits apply to the Web Property / Property / Tracking ID. 10 million hits per month per property If you go over this limit, the Google Analytics team might contact you and ask you upgrade to Premium or implement client sampling to reduce the amount of data being sent to Google Analytics. However, I note that there is nothing to say that you can review or check up on your current usage for the month. I have administrator access to the Google Analytics account, but I see no feature that lets me check up on my monthly usage. I don't know if Google offer this, either by means of the admin interface or via their support channels - but it would certainly be a useful feature. Is there anyway for a free GA user to obtain this information?

• Setup Convergence Address Book DisplayName Lookup

  - by user13332755

  At Convergence Address Book the default lookup for 'Display Name' is the LDAP attribute 'cn', which leads into confusion if you start to setup 'displayName' LDAP attributes for your users. LDAP User Entry with diaplyName attribute: This behavior can be controlled by the configuration file xlate-inetorgperson.xml. Change the default value of XPATH abperson\entry\displayname from 'cn' to 'displayName'. <convergence_deploy_location>/config/templates/ab/corp-dir/xlate-inetorgperson.xml Note: In case the user has no 'displayName' attribute in LDAP you might noticed '...' at the user entry, if found via 'mail' attribute.

• Convert filenames to their checksum before saving to prevent duplicates. Is is a smart thing to do?

  - by Xananax

  TL;DR:what the title says I am developing some sort of image board in PHP. I was thinking of changing each image's filename to it's checksum prior to saving it. This way, I might be able to prevent duplicates. I know this wouldn't work for two images that are the same but differ in size or level of compression or whatnot, but this method would allow for an early check. What bugs me is that I never saw this method implemented anywhere, so I was wondering if there is a catch to it. Maybe it is just more efficient to keep the original filename and store the hash in DB? Maybe the whole method is just not useful and my question is moot? What do you think? On a side note, I don't really get how hashes are calculated so I was wondering, if my first question checks out, if it would be possible to calculate the likeness that two images are similar by comparing hashes (levenshtein or something of the sort).

• Expanding your home directory size

  - by myusuf3

  I would like to copy or expand my /home directory ... All tutorials talks about moving the home directory from a partition to another but the problem that I only have one partition that was more than 300 gigs (before I resize it and create a new partition) although I see 30 Gigs only on my home directory (4 Gigs left :( ) I resized it and created a new partition as you can see in the next image I've tried booting from Ubuntu live CD and from a USB and what I can see in Gparted is exactly as in the picture below I would like to move my home directory to the new partition of expand it. This is a snapshot of what I can see on my Gparted (note: the new partition is never used I just created it) http://www.ps-revolution.net/pic/afc3cbbf9f1ba853b2d62f03cf132e8c.png This is from Disk Utilities http://www.ps-revolution.net/pic/d40aa2975f8b1679d867f7ef2587089b.png Thanks in Advance

• Flash Webcam non responsive Ubuntu 11.10

  - by powerbuoy

  I've got the same problem as this gentleman: https://answers.launchpad.net/ubuntu/+source/flashplugin-nonfree/+question/176541 Where the webcam settings / access does not work at all / is completely unresponsive in Ubuntu 11.10. I've tried webcam access in Facebook, Google+, my own code + a number of tutorials/demos and none work. What happens is the settings dialogue is completely unresponsive. Clicking tabs or buttons does nothing. In the question linked to a suggested answer is to run Unity 2D. Unfortunately this does not work for me (the exact same thing happens). I've also tried Gnome 3 which also does not work. Note that it is only the webcam settings that don't work. YouTube videos and annoying banners work just fine. Does anyone know of a workaround for this (except going back to 11.04) or if they've fixed this in 12.04? - also, are any of you experiencing the same thing?

• 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 there a difference between "." and "source" in bash, after all?

  - by ysap

  I was looking for the difference between the "." and "source" builtin commands and a few sources (e.g., in this discussion, and the bash manpage) suggest that these are just the same. However, following a problem with environment variables, I conducted a test. I created a file testenv.sh that contains: #!/bin/bash echo $MY_VAR In the command prompt, I performed the following: > chmod +x testenv.sh > MY_VAR=12345 > ./testenv.sh > source testenv.sh 12345 > MY_VAR=12345 ./testenv.sh 12345 [note that the 1st form returned an empty string] So, this little experiment suggests that there is a difference after all, where for the "source" command, the child environment inherits all the variables from the parent one, where for the "." it does not. Am I missing something, or is this is an undocumented/deprecated feature of bash? [ GNU bash, version 4.1.5(1)-release (x86_64-pc-linux-gnu) ]
