  • How do tight timelines and scheduling pressure affect TCO and delivery time?

    - by JonathanHayward
    A friend's father, who is a software engineering manager, said, emphatically, "The number one cause of scheduling overruns is scheduling pressure." Where does the research stand? Is a moderate amount of scheduling pressure invigorating, or is the manager I mentioned right or wrong, or is it a matter of "the more scheduling pressure you have, the longer the delivery time and the more TCO?" Is it one of those things where ideally software engineering would work without scheduling pressure but practically we have to work with constraints of real-world situations? Any links to software engineering literature would be appreciated.

  • Sony VAIO with Insyde H2O EFI bios will not boot into GRUB EFI

    - by Rohan Dhruva
    I bought a new Sony Vaio S series laptop. It uses Insyde H2O BIOS EFI, and trying to install Linux on it is driving me crazy. root@kubuntu:~# parted /dev/sda print Model: ATA Hitachi HTS72756 (scsi) Disk /dev/sda: 640GB Sector size (logical/physical): 512B/4096B Partition Table: gpt Number Start End Size File system Name Flags 1 1049kB 274MB 273MB fat32 EFI system partition hidden 2 274MB 20.8GB 20.6GB ntfs Basic data partition hidden, diag 3 20.8GB 21.1GB 273MB fat32 EFI system partition boot 4 21.1GB 21.3GB 134MB Microsoft reserved partition msftres 5 21.3GB 342GB 320GB ntfs Basic data partition 6 342GB 358GB 16.1GB ext4 Basic data partition 7 358GB 374GB 16.1GB ntfs Basic data partition 8 374GB 640GB 266GB ntfs Basic data partition What is surprising is that there are 2 EFI system partitions on the disk. The sda2 partition is a 20gb recovery partition which loads windows with a basic recovery interface. This is accessible by pressing the "ASSIST" button as opposed to the normal power button. I presume that the sda1 EFI System Partition (ESP) loads into this recovery. The sda3 ESP has more fleshed out entries for Microsoft Windows, which actually goes into Windows 7 (as confirmed by bcdedit.exe on Windows). Ubuntu is installed on sda6, and while installation I chose sda3 as my boot partition. The installer correctly created a sda3/EFI/ubuntu/grubx64.efi application. The real problem: for the life of me, I can't set it to be the default! I tried creating a sda3/startup.nsh which called grubx64.efi, but it didn't help -- on rebooting, the system still boots into windows. I tried using efibootmgr, and that shows as it it worked: root@kubuntu:~# efibootmgr BootCurrent: 0000 BootOrder: 0000,0001 Boot0000* EFI USB Device Boot0001* Windows Boot Manager root@kubuntu:~# efibootmgr --create --gpt --disk /dev/sda --part 3 --write-signature --label "GRUB2" --loader "\\EFI\\ubuntu\\grubx64.efi" BootCurrent: 0000 BootOrder: 0002,0000,0001 Boot0000* EFI USB Device Boot0001* Windows Boot Manager Boot0002* GRUB2 root@kubuntu:~# efibootmgr BootCurrent: 0000 BootOrder: 0002,0000,0001 Boot0000* EFI USB Device Boot0001* Windows Boot Manager Boot0002* GRUB2 However, on rebooting, as you guessed, the machine rebooted directly back into Windows. The only things I can think of are: The sda1 partition is somehow being used Overwrite /EFI/Boot/bootx64.efi and /EFI/Microsoft/Boot/bootmgfw.efi with grubx64.efi [but this seems really radical]. Can anyone please help me out? Thanks -- any help is greatly appreciated, as this issue is driving me crazy!

  • SQL SERVER – Order By Numeric Values Formatted as String

    - by pinaldave
    When I was writing this blog post I had a hard time to come up with the title of the blog post so I did my best to come up with one. Here is the reason why? I wrote a blog post earlier SQL SERVER – Find First Non-Numeric Character from String. One of the questions was that how that blog can be useful in real life scenario. This blog post is the answer to that question. Let us first see a problem. We have a table which has a column containing alphanumeric data. The data always has first as an integer and later part as a string. The business need is to order the data based on the first part of the alphanumeric data which is an integer. Now the problem is that no matter how we use ORDER BY the result is not produced as expected. Let us understand this with example. Prepare a sample data: -- How to find first non numberic character USE tempdb GO CREATE TABLE MyTable (ID INT, Col1 VARCHAR(100)) GO INSERT INTO MyTable (ID, Col1) SELECT 1, '1one' UNION ALL SELECT 2, '11eleven' UNION ALL SELECT 3, '2two' UNION ALL SELECT 4, '22twentytwo' UNION ALL SELECT 5, '111oneeleven' GO -- Select Data SELECT * FROM MyTable GO The above query will give following result set. Now let us use ORDER BY COL1 and observe the result along with Original SELECT. -- Select Data SELECT * FROM MyTable GO -- Select Data SELECT * FROM MyTable ORDER BY Col1 GO The result of the table is not as per expected. We need the result in following format. Here is the good example of how we can use PATINDEX. -- Use of PATINDEX SELECT ID, LEFT(Col1,PATINDEX('%[^0-9]%',Col1)-1) 'Numeric Character', Col1 'Original Character' FROM MyTable ORDER BY LEFT(Col1,PATINDEX('%[^0-9]%',Col1)-1) GO We can use PATINDEX to identify the length of the digit part in the alphanumeric string (Remember: Our string has a first part as an int always. It will not work in any other scenario). Now you can use the LEFT function to extract the INT portion from the alphanumeric string and order the data according to it. You can easily clean up the script by dropping following table. DROP TABLE MyTable GO Here is the complete script so you can easily refer it. -- How to find first non numberic character USE tempdb GO CREATE TABLE MyTable (ID INT, Col1 VARCHAR(100)) GO INSERT INTO MyTable (ID, Col1) SELECT 1, '1one' UNION ALL SELECT 2, '11eleven' UNION ALL SELECT 3, '2two' UNION ALL SELECT 4, '22twentytwo' UNION ALL SELECT 5, '111oneeleven' GO -- Select Data SELECT * FROM MyTable GO -- Select Data SELECT * FROM MyTable ORDER BY Col1 GO -- Use of PATINDEX SELECT ID, Col1 'Original Character' FROM MyTable ORDER BY LEFT(Col1,PATINDEX('%[^0-9]%',Col1)-1) GO DROP TABLE MyTable GO Well, isn’t it an interesting solution. Any suggestion for better solution? Additionally any suggestion for changing the title of this blog post?

  • How to Install KVM and Create Virtual Machines on Ubuntu

    - by Chris Hoffman
    If you’re using Linux, you don’t need VirtualBox or VMware to create virtual machines. You can use KVM – the kernel-based virtual machine – to run both Windows and Linux in virtual machines. You can use KVM directly or with other command-line tools, but the graphical Virtual Machine Manager (Virt-Manager) application will feel most familiar to people that have used other virtual machine programs.

  • Can a Printer Print White?

    - by Jason Fitzpatrick
    The vast majority of the time we all print on white media: white paper, white cardstock, and other neutral white surfaces. But what about printing white? Can modern printers print white and if not, why not? Read on as we explore color theory, printer design choices, and why white is the foundation of the printing process. Today’s Question & Answer session comes to us courtesy of SuperUser—a subdivision of Stack Exchange, a community-driven grouping of Q&A web sites. Image by Coiote O.; available as wallpaper here. The Question SuperUser reader Curious_Kid is well, curious, about printers. He writes: I was reading about different color models, when this question hit my mind. Can the CMYK color model generate white color? Printers use CMYK color mode. What will happen if I try to print a white colored image (rabbit) on a black paper with my printer? Will I get any image on the paper? Does the CMYK color model have room for white? The Answer SuperUser contributor Darth Android offers some insight into the CMYK process: You will not get anything on the paper with a basic CMYK inkjet or laser printer. The CMYK color mixing is subtractive, meaning that it requires the base that is being colored to have all colors (i.e., White) So that it can create color variation through subtraction: White - Cyan - Yellow = Green White - Yellow - Magenta = Red White - Cyan - Magenta = Blue White is represented as 0 cyan, 0 yellow, 0 magenta, and 0 black – effectively, 0 ink for a printer that simply has those four cartridges. This works great when you have white media, as “printing no ink” simply leaves the white exposed, but as you can imagine, this doesn’t work for non-white media. If you don’t have a base color to subtract from (i.e., Black), then it doesn’t matter what you subtract from it, you still have the color Black. [But], as others are pointing out, there are special printers which can operate in the CMYW color space, or otherwise have a white ink or toner. These can be used to print light colors on top of dark or otherwise non-white media. You might also find my answer to a different question about color spaces helpful or informative. Given that the majority of printer media in the world is white and printing pure white on non-white colors is a specialty process, it’s no surprise that home and (most) commercial printers alike have no provision for it. Have something to add to the explanation? Sound off in the the comments. Want to read more answers from other tech-savvy Stack Exchange users? Check out the full discussion thread here.

  • Bluetooth fix for Ubuntu 12.04, lenovo G580

    - by Sam Abraham
    Bluetooth not working, it shows turned on but manager indicated Bluetooth disabled. Uninstalled default manager and installed Blueman. The same with Blueman, clicking on connect to devices gets response 'adapters not found'. I've found many more people with the same problem. The fixes found in the archive don't work for me. I've tried a couple of things from the forum. I'm not familiar with computer hardware or software but have been using Ubuntu cause it saves me money, it's fairly easy to use and it does not tax my mid-range lap. Any help will be appreciated.

  • Can't connect to STunnel when it's running as a service

    - by John Francis
    I've got STunnel configured to proxy non SSL POP3 requests to GMail on port 111. This is working fine when STunnel is running as a desktop app, but when I run the STunnel service, I can't connect to port 111 on the machine (using Outlook Express for example). The Stunnel log file shows the port binding is succeeding, but it never sees a connection. There's something preventing the connection to that port when STunnel is running as a service? Here's stunnel.conf cert = stunnel.pem ; Some performance tunings socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 ; Some debugging stuff useful for troubleshooting debug = 7 output = stunnel.log ;

It's written in python and uses flask as its framework. I'd like to share this with other employees and beta testers (<25 people). Ideally, I could get some sort of simple hosting space/service and push regular updates to it while we test and iterate on this app. Think something along the lines of dropbox, which of course would not work for this purpose. We do have a website, and hosting services for it, but I'm concerned about using this resource as our website is mission critical and this app is very much pre-alpha at this point. Options I've researched / considered Self host from local machine/network (slow, unreliable) Purchase hosting space (with limited non-profit resources, I'm concerned this is overkill) Using our current web server / hosting (not appropriate for testing) Thanks very much for your time!

  • Reflections on GiveCamp

    - by Reed
    I participated in the Seattle GiveCamp over the weekend, and am entirely impressed.  GiveCamp is a great event – I especially like how rewarding it is for everybody involved.  I strongly encourage any and all developers to watch for future GiveCamp events, and consider participating, for many reasons… GiveCamp provides real value to organizations that truly need help.  The Seattle event alone succeeded in helping sixteen non-profit organizations in many different ways.  The projects involved varied dramatically, including website redesigns, SEO, reworking data management workflows, and even game development.  Many non-profits have a strong need for good, quality technical help.  However, nearly every non-profit organization has an incredibly limited budget.  GiveCamp is a way to really give back, and provide incredibly valuable help to organizations that truly benefit. My experience has shown many developers to be incredibly generous – this is a chance to dedicate your energy to helping others in a way that really takes advantage of your expertise.  Your time as a developer is incredibly valuable, and this puts something of incredible value directly into the hands of places its needed. First, and foremost, GiveCamp is about providing technical help to non-profit organizations in need. GiveCamp can make you a better developer.  This is a fantastic opportunity for us, as developers, to work with new people, in a new setting.  The incredibly short time frame (one weekend for a deliverable project) and intense motivation to succeed provides a huge opportunity for learning from peers.  I’d personally like to thank off the developers with whom I worked – I learned something from each and every one of you.  I hope to see and work with all of you again someday. GiveCamp provides an opportunity for you to work outside of your comfort zone. While it’s always nice to be an expert, it’s also valuable to work on a project where you have little or no direct experience.  My team focused on a complete reworking of our organizations message and a complete new website redesign and deployment using WordPress.  While I’d used WordPress for my blog, and had some experience, this is completely unrelated to my professional work.  In fact, nobody on our team normally worked directly with the technologies involved – yet together we managed to succeed in delivering our goals.  As developers, it’s easy to want to stay abreast of new technology surrounding our expertise, but its rare that we get a chance to sit down and work on something practical that is completely outside of our normal realm of work.  I’m a desktop developer by trade, and spent much of the weekend working with CSS and Photoshop.  Many of the projects organizations need don’t match perfectly with the skill set in the room – yet all of the software professionals rose to the occasion and delivered practical, usable applications. GiveCamp is a short term, known commitment. While this seems obvious, I think it’s an important aspect to remember.  This is a huge part of what makes it successful – you can work, completely focused, on a project, then walk away completely when you’re done.  There is no expectation of continued involvement.  While many of the professionals I’ve talked to are willing to contribute some amount of their time beyond the camp, this is not expected. The freedom this provides is immense.  In addition, the motivation this brings is incredibly valuable.  Every developer in the room was very focused on delivering in time – you have one shot to get it as good as possible, and leave it with the organization in a way that can be maintained by them.  This is a rare experience – and excellent practice at time management for everyone involved. GiveCamp provides a great way to meet and network with your peers. Not only do you get to network with other software professionals in your area – you get to network with amazing people.  Every single person in the room is there to try to help people.  The balance of altruism, intelligence, and expertise in the room is something I’ve never before experienced. During the presentations of what was accomplished, I felt blessed to participate.  I know many people in the room were incredibly touched by the level of dedication and accomplishment over the weekend. GiveCamp is fun. At the end of the experience, I would have signed up again, even if it was a painful, tedious weekend – merely due to the amazing accomplishments achieved throughout the event.  However, the event is fun.  Everybody I talked to, the entire weekend, was having a good time.  While there were many faces focused into a near grimace at times (including mine, I’ll admit), this was always in response to a particularly challenging problem or task.  The challenges just added to the overall enjoyment of the weekend – part of why I became a developer in the first place is my love for challenge and puzzles, and a short deadline using unfamiliar technology provided plenty of opportunity for puzzles.  As soon as people would stand up, it was another smile.   If you’re a developer, I’d recommend looking at GiveCamp more closely.  Watch for an event in your area.  If there isn’t one, consider building a team and organizing an event.  The experience is worth the commitment.

  • Generic and type safe I/O model in any language

    - by Eduardo León
    I am looking for an I/O model, in any programming language, that is generic and type safe. By genericity, I mean there should not be separate functions for performing the same operations on different devices (read_file, read_socket, read_terminal). Instead, a single read operation works on all read-able devices, a single write operation works on all write-able devices, and so on. By type safety, I mean operations that do not make sense should not even be expressible in first place. Using the read operation on a non-read-able device ought to cause a type error at compile time, similarly for using the write operation on a non-write-able device, and so on. Is there any generic and type safe I/O model?

  • UndoRedo on Nodes

    - by Geertjan
    When a change is made to the property in the Properties Window, below, the undo/redo functionality becomes enabled: When undo/redo are invoked, e.g., via the buttons in the toolbar, the display name of the node changes accordingly. The only problem I have is that the buttons only become enabled when the Person Window is selected, not when the Properties Window is selected, which would be desirable. Here's the Person object: public class Person implements PropertyChangeListener {     private String name;     public static final String PROP_NAME = "name";     public Person(String name) {         this.name = name;     }     public String getName() {         return name;     }     public void setName(String name) {         String oldName = this.name;         this.name = name;         propertyChangeSupport.firePropertyChange(PROP_NAME, oldName, name);     }     private transient final PropertyChangeSupport propertyChangeSupport = new PropertyChangeSupport(this);     public void addPropertyChangeListener(PropertyChangeListener listener) {         propertyChangeSupport.addPropertyChangeListener(listener);     }     public void removePropertyChangeListener(PropertyChangeListener listener) {         propertyChangeSupport.removePropertyChangeListener(listener);     }     @Override     public void propertyChange(PropertyChangeEvent evt) {         propertyChangeSupport.firePropertyChange(evt);     } } And here's the Node with UndoRedo enablement: public class PersonNode extends AbstractNode implements UndoRedo.Provider, PropertyChangeListener {     private UndoRedo.Manager manager = new UndoRedo.Manager();     private boolean undoRedoEvent;     public PersonNode(Person person) {         super(Children.LEAF, Lookups.singleton(person));         person.addPropertyChangeListener(this);         setDisplayName(person.getName());     }     @Override     protected Sheet createSheet() {         Sheet sheet = Sheet.createDefault();         Sheet.Set set = Sheet.createPropertiesSet();         set.put(new NameProperty(getLookup().lookup(Person.class)));         sheet.put(set);         return sheet;     }     @Override     public void propertyChange(PropertyChangeEvent evt) {         if (evt.getPropertyName().equals(Person.PROP_NAME)) {             firePropertyChange(evt.getPropertyName(), evt.getOldValue(), evt.getNewValue());         }     }     public void fireUndoableEvent(String property, Person source, Object oldValue, Object newValue) {         manager.addEdit(new MyAbstractUndoableEdit(source, oldValue, newValue));     }     @Override     public UndoRedo getUndoRedo() {         return manager;     }     @Override     public String getDisplayName() {         Person p = getLookup().lookup(Person.class);         if (p != null) {             return p.getName();         }         return super.getDisplayName();     }     private class NameProperty extends PropertySupport.ReadWrite<String> {         private Person p;         public NameProperty(Person p) {             super("name", String.class, "Name", "Name of Person");             this.p = p;         }         @Override         public String getValue() throws IllegalAccessException, InvocationTargetException {             return p.getName();         }         @Override         public void setValue(String newValue) throws IllegalAccessException, IllegalArgumentException, InvocationTargetException {             String oldValue = p.getName();             p.setName(newValue);             if (!undoRedoEvent) {                 fireUndoableEvent("name", p, oldValue, newValue);                 fireDisplayNameChange(oldValue, newValue);             }         }     }     class MyAbstractUndoableEdit extends AbstractUndoableEdit {         private final String oldValue;         private final String newValue;         private final Person source;         private MyAbstractUndoableEdit(Person source, Object oldValue, Object newValue) {             this.oldValue = oldValue.toString();             this.newValue = newValue.toString();             this.source = source;         }         @Override         public boolean canRedo() {             return true;         }         @Override         public boolean canUndo() {             return true;         }         @Override         public void undo() throws CannotUndoException {             undoRedoEvent = true;             source.setName(oldValue.toString());             fireDisplayNameChange(oldValue, newValue);             undoRedoEvent = false;         }         @Override         public void redo() throws CannotUndoException {             undoRedoEvent = true;             source.setName(newValue.toString());             fireDisplayNameChange(oldValue, newValue);             undoRedoEvent = false;         }     } } Does anyone out there know how to have the Undo/Redo functionality enabled when the Properties Window is selected?

  • Who Makes a Good Product Owner

    - by Robert May
    In general, the best product owners are those that care passionately about the customer of the product.  Note that I didn’t say about the product itself.  Actually, people that only care about the product, generally do not make good product owners.  Products only matter in relationship to their customers.  If a product doesn’t provide value to the customer, then the product has no value, no matter what a person might think of the product, and no matter what cool technologies exist inside of the product. A good product owner is also a good negotiator.  They recognize that many different priorities exist inside of a corporation, but that there can be only one list that developers work from.  A good product owner recognizes that its their job to help others around them prioritize (perhaps with a Product Council), but also understand that they alone have the final say about priorities and are willing to make the tough decisions required.  Deciding the priority between two perfectly valid stories is very difficult, especially when the stories are from two different departments! A good product owner is deeply interested in helping the team be successful.  They don’t seek to control the team, but instead seek to understand what the team can do and then work with the team to get the best product possible for the Customer.  A good product owner is never denigrating to team members, ever.  They recognize that such behavior would damage the trust that needs to be present between team members and product owners and will avoid it at all costs. In general, technical people (i.e. former or current developers) make poor product owners.  In their minds, they can’t separate implementation details from user functionality, so their stories end up sounding like implementation details.  For example, “The user enters their username on the password screen” is something that a technical product owner would write.  The proper wording for that story is “A user supplies the system with their credentials.”  Because technical people think different from the rest of the population, they are generally not a good fit. A good product owner is also a good writer.  Writing good stories demands good writing.  The art of persuasion, descriptiveness and just general good grammar are all required.  A good Product Owner must also be well spoken, since most of what will be conveyed will be conveyed with the spoken word, not just written word. A good product owner is a “People Person.”  They like talking to people and are very patient.  They don’t mind having questions repeated or fielding many questions, because they want to make sure that the ideas they’re conveying are properly understood so the customer gets the best product possible.  They are happy to answer any questions a team member may have and invite feedback and criticism of designs and stories, since they want a good product.  They really have little ego that gets in the way of building a great product. All of these qualities can be hard to find, but if you look close enough, you’ll find the right person in your organization.  Product owners can be found anywhere, not just in upper management.  Some of the best product owners are those that are very close to the customer.  In fact, check your customer support staff.  I’d bet that several great product owners are lurking there. Final note about what makes a good product owner.  You’re probably NOT going to find a good product owner in a manager, especially if they consider themselves a “Manager.”  Product owners don’t manage anything but the backlog, so be especially careful if the person you’re selecting for Product Owner is a manager.

  • Ubuntu 11.10 with KDE installed does not prompt for elevation for privileged ops in all apps

    - by Michael Goldshteyn
    I installed the KDE window manager on top of Ubuntu 11.10 and while I am using KDE, I do not get an elevation dialog when I try to perform tasks that require root privileges. Instead, the operations silently fail, unless I launch apps from a terminal, in which case I get errors like: Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/softwareproperties/gtk/SoftwarePropertiesGtk.py", line 649, in on_isv_source_toggled self.backend.ToggleSourceUse(str(source_entry)) File "/usr/lib/python2.7/dist-packages/dbus/proxies.py", line 143, in __call__ **keywords) File "/usr/lib/python2.7/dist-packages/dbus/connection.py", line 630, in call_blocking message, timeout) dbus.exceptions.DBusException: com.ubuntu.SoftwareProperties.PermissionDeniedByPolicy: com.ubuntu.softwareproperties.applychanges Or from the muon package manager, an error dialog such as: Does anyone know what I need to do to fix this, so that I get a proper dialog asking for elevation? Otherwise, I have to start each app that may need root privs with sudo from a terminal or gksudo. Thanks

  • I attempted to install cuda drivers, and now almost everything is broken

    - by Nathan
    I tried to install CUDA tookit 5.0 on ubuntu 12.04 and the installation proceeded OK. After rebooting however, all I get is a terminal login. I've attempted to start the display manager with sudo start lightdm and it says all OK, but just hangs the prompt when it finishes loading without ever starting any display manager. sudo start gdm just flickers and goes back to the prompt. There is no network connection on the machine either. It usually connects to a wireless network with remembered credentials. What can I do to recover the machine?

  • Transferring at a large software company: ask boss before or after?

    - by ZNZ
    Out of college I joined a large, well-known software company's consulting arm. I've gained lots of experience with some of the company's products but would like to start doing more development work rather than implementation work (traveling less would be nice, too!). The company has some product development positions that I think I could be a good fit for, but I'm unsure of how to bring it up with my manager. After a bit Googling, there are many conflicted answers on how best to handle transferring departments. When should I tell my current manager that I am interested in pursuing other positions in the company? Before or after applying?
