  • Tell me a Story

    - by Geoff N. Hiten
    I recently had a friend ask me to review his resume.  He is a very experienced DBA with excellent skills.  If I had an opening I would have hired him myself.  But not because of the resume.  I know his skill set and skill levels, but there is no way his standard resume can convey that.  A bare bones list of job titles and skills does not set you apart from your competition, nor does it convey whether you have junior or senior level skills and experience.  The solution is to not use the standard format. Tell me a story.  I want to know what you were responsible for.  Describe a tough project and how you saved time/money/personnel on that project.  Link your work activity to business value.  Drop some technical bits in there since we do work in a technical field, but show me what you can do to add value to my business well above what I would pay you.  That will get my attention. The resume exists for one primary and one secondary reason.  The primary reason is to get the interview.  A Resume won’t get you a job, so don’t expect it to.  The secondary reason is to give you and the interviewer a starting point for conversations.  If I can say “Tell me more about when….” and reference an item from your resume, then that is great for both of us.  Of course, you better be able to tell me more, both from the technical and the business side, at least if I am hiring a senior or higher level position.  As for the junior DBAs, go ahead and tell your story too.  Don’t worry about how simple or basic your projects or solutions seem.  It is how you solved the problem and what you learned that I am looking for.  If you learn rapidly and think like a DBA, I can work with that, regardless of you current skill level.

  • Should Git be used for documentation and project management? Should the code be in a separate repository?

    - by EmpireJones
    I'm starting up a Git repository for a group project. Does it make sense to store documents in the same Git repository as code - it seems like this conflicts with the nature of the git revision flow. Here is a summary of my question(s): Is the Git revisioning style going to be confusing if both code and documents are checked into the same repository? Experiences with this? Is Git a good fit for documentation revision control? I am NOT asking if a Revision Control System in general should or shouldn't be used for documentation - it should. Thanks for the feedback so far!

  • OUYA and Unity set up problems

    - by Atkobeau
    I'm having trouble with the Unity / OUYA plugin. I'm using Unity 4 with the latest update on a Windows 7 machine. When I open the starter kit and try to compile the plugin I get the following error: Picked up _JAVA_OPTIONS: -Xmx512M And if I try to Build and Run I get this error: Error building Player: ArgumentException: Illegal characters in path. I'm stumped, I've gone through lots of forum posts here and on stackoverflow and I can't seem to resolve it. My environment variables look like this: PATH - C:\Users\dave\Documents\adt-bundle-windows-x86_64-20130219\sdk\tools; C:\Users\dave\Documents\adt-bundle-windows-x86_64-20130219\sdk\platform-tools\ JAVA_HOME - C:\Program Files (x86)\Java\jdk1.6.0_45\ Everything in the OUYA Panel is white Any ideas?

  • Unity dash search

    - by To Do
    I have my personal folders to a different partition other than home, I had a series of symlinks in my home folder pointing to the folders on the other partition. This was causing multiple entries in Dash search do I modified my ~/.config/user-dirs.dirs file pointing them to the folders on the second partition. The issue is that when I search for any one of these folders in Dash, I still get two entries, one pointing the folder and another that points to the /home/username/Documents folder. If I click on this link I get a Could not find /home/username/Documents error. Why is this and how do I delete these entries from Dash's records? If deleting records is not possible, is there a way to "reindex" the dash search database?

  • SQL: empty string vs NULL value

    - by Jacek Prucia
    I know this subject is a bit controversial and there are a lot of various articles/opinions floating around the internet. Unfortunatelly, most of them assume the person doesn't know what the difference between NULL and empty string is. So they tell stories about surprising results with joins/aggregates and generally do a bit more advanced SQL lessons. By doing this, they absolutely miss the whole point and are therefore useless for me. So hopefully this question and all answers will move subject a bit forward. Let's suppose I have a table with personal information (name, birth, etc) where one of the columns is an email address with varchar type. We assume that for some reason some people might not want to provide an email address. When inserting such data (without email) into the table, there are two available choices: set cell to NULL or set it to empty string (''). Let's assume that I'm aware of all the technical implications of choosing one solution over another and I can create correct SQL queries for either scenario. The problem is even when both values differ on the technical level, they are exactly the same on logical level. After looking at NULL and '' I came to a single conclusion: I don't know email address of the guy. Also no matter how hard i tried, I was not able to sent an e-mail using either NULL or empty string, so apparently most SMTP servers out there agree with my logic. So i tend to use NULL where i don't know the value and consider empty string a bad thing. After some intense discussions with colleagues i came with two questions: am I right in assuming that using empty string for an unknown value is causing a database to "lie" about the facts? To be more precise: using SQL's idea of what is value and what is not, I might come to conclusion: we have e-mail address, just by finding out it is not null. But then later on, when trying to send e-mail I'll come to contradictory conclusion: no, we don't have e-mail address, that @!#$ Database must have been lying! Is there any logical scenario in which an empty string '' could be such a good carrier of important information (besides value and no value), which would be troublesome/inefficient to store by any other way (like additional column). I've seen many posts claiming that sometimes it's good to use empty string along with real values and NULLs, but so far haven't seen a scenario that would be logical (in terms of SQL/DB design). P.S. Some people will be tempted to answer, that it is just a matter of personal taste. I don't agree. To me it is a design decision with important consequences. So i'd like to see answers where opion about this is backed by some logical and/or technical reasons.

  • User eXperience

    - by Daniel Moth
    The last few months I have been spending a lot of time designing (and help design) the developer experience for the areas I contribute to (in future versions of Visual Studio). As a technical person who defines feature sets, it is easy to get engulfed in the pure technical side of things and ignore the details that ultimately make users "love" using the product to achieve their goal, instead of just "having to use" it. Engaging in UX design helps me escape that trap. In case you are also interested in the UX side of development, I thought I'd share an interesting site I came across: UX myths. In particular, I recommend reading myths 9, 10, 12, 13, 14, 15 and 21. Let me know if there are other UX resources you recommend… Comments about this post welcome at the original blog.

  • Auto-run script when iPad plugged in

    - by oldmankit
    The way that Ubuntu handles documents on the iPad is awesome (without any configuration required). It beats windows, even after you install iTunes. I want to have the documents in certain iPad apps automatically synced into my Dropbox directory whenever the iPad is connected by USB. The syncing is easy; getting the script to run is not. I have already read the information in various (very out-of-date) tutorials. The best I could find was here: http://askubuntu.com/a/25091/16157 I used lsusb, with the following results: Bus 002 Device 012: ID 05ac:12a2 Apple, Inc. (Please note that when an iPad is connected, Ubuntu seems to mount it to two different mount points: one for "Documents" and one for the whole iPad filesystem. They are both mounted in ~/.gvfs) I have created the following file /etc/udev/rules.d/96-ipad_sync.rules ACTION=="add", ATTRS{idVendor}=="05ac", ATTRS{idProduct}=="12a2", RUN+="/home/kit/bin/jobdone2" I want it to run a test script (which sleeps for five seconds then plays an mp3 file. The test script works, and I have typed the location correctly). So far, when I plug the iPad in, nothing happens. Yes, I waited five seconds. This is the output I get from typing udevadm monitor –env KERNEL[29348.114010] add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.4 (usb) KERNEL[29348.114844] add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.4/2-1.4:1.0 (usb) KERNEL[29348.129118] remove /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.4/2-1.4:1.0 (usb) KERNEL[29348.130699] add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.4/2-1.4:4.0 (usb) KERNEL[29348.130845] add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.4/2-1.4:4.1 (usb) KERNEL[29348.130909] add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.4/2-1.4:4.2 (usb) UDEV [29348.163861] add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.4 (usb) UDEV [29348.170390] add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.4/2-1.4:1.0 (usb) UDEV [29348.171521] add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.4/2-1.4:4.1 (usb) UDEV [29348.172230] remove /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.4/2-1.4:1.0 (usb) UDEV [29348.172890] add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.4/2-1.4:4.2 (usb) UDEV [29348.175645] add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.4/2-1.4:4.0 (usb)

  • Best sites to find good .NET Developers

    - by Mag20
    I am looking for good sites to post a position for a .NET developer. I already tried: Craig's list got about 10 resumes, but most couldn't answer our technical questions StackOverflow Careers no responses What sites did you have success with finding good developers? UPDATE 1: Wanted to provide some more information: My company is in NJ. We are a small startup. Less then 10 people. Monster, Dice, CareerBuilder all charge like $500 a month per posting. Seems a bit much. Also only Dice is specifically targeting technical positions. With monster and career builder I am a bit worried about having to go through hundreds of resumes that don't apply.

  • Where can I find game postmortems with a programmer perspective [on hold]

    - by Ken
    There are a number of interesting game post-mortems in places like GDC vault or gamastura.com. The post-mortems are generally give with a CEO/manager perspective or a designer perspective, or, more often a combination of both e.g DOOM postmortem But I have not been able to find many post-mortems which are primarily from the programmers perspective. I'm looking for discussions and rational for technical choices and tradeoffs and how technical problems were overcome. The motivation here is to learn what kind of problems real game programmers encounter and how they go about solving them. A perfect example of what I'm looking for is Renaud Bédard's excellent GDC talk on the development of Fez, "Cubes all the way down". Where can I find more like that?

  • Wiki based requirements engineering tool

    - by Shanon
    Hi, I'm looking to to build a wiki based tool the helps/aides in the requirements engineering process. More specifically I am hoping to end up with a tool that helps inexperienced users easily create and design requirements documents on a wiki platform. I was wondering if there exist any wiki/wiki platforms that either already exist or are easily extendible or would be worth looking at that for this purpose. For instance some of the features I was hoping to add would be to add structure to a document so that information is filled out in a standardised manner. Another idea I was looking at was to somehow create relationships between different types of documents (for example- a goal diagram gets evolves/ helps in the development of the class diagram). So far I have come across FOSwiki which claims to to fully customisalble...but I'm not sure what it means and what I can really do with that. Any input on FOSwiki is also highly appreciated.

  • Architects, Leadership, and Influence

    - by Bob Rhubart
    Technical expertise is a given for architects. In addition to solid development experience, extensive knowledge of technical trends, tools, standards, and methodolgies (not to mention business accumen) provides the foundation for the decisions the architect must make in the effort to get all the pieces to work together. But even superior technical chops can't overcome a lack of leadership. Leadership is about influence: the ability to effectively communicate — to sell your ideas and defend your decisions in a manner that affects the decisions of the people around you. Leadership and influence are especially important in situations in which the architect may not have the authority to simply tell people what to do. And even when the architect has that kind of authority, influential leadership can mean the difference between gaining real buy-in and support from colleagues and stakeholders, and settling for their grudging acceptance (or worse). Guess which outcome is likely to produce the best results. In a previous post I presented some examples of the kind of criticism that is leveled at architects, a great deal of which can be attributed to a lack of leadership and influence on the part of the targets of that criticism. So it was serendipitous that I recently ran across a post on the Harvard Business Review blog written by Chris Musselwhite and Tammie Plouffe. That post, When Your Influence Is Ineffective, includes this: [I]nfluence becomes ineffective when individuals become so focused on the desired outcome that they fail to fully consider the situation. While the influencer may still gain the short-term desired outcome, he or she can do long-term damage to personal effectiveness and the organization, as it creates an atmosphere of distrust where people stop listening, and the potential for innovation or progress is diminished. The need to "see the big picture" is a grossly reductive assesement of the architect's responsibilities — but that doesn't mean it's not true. That big picture perspective must encompass both the technological elements of the architecture and the elements responsible for implementing those technologies in compliance with the prescribed architecture. Technologies may be tempermental, but they don't have personalities or egos, and they are unlikely to carry a grudge — not yet, anyway (Hello, Skynet!).  Effective leadership and the ability to influence people can help to ensure that all the pieces fit and that they work together, today and tomorrow.

  • Random MongoDb Syntax: Updates

    - by Liam McLennan
    I have a MongoDb collection called tweets. Each document has a property system_classification. If the value of system_classification is ‘+’ I want to change it to ‘positive’. For a regular relational database the query would be: update tweets set system_classification = 'positive' where system_classification = '+' the MongoDb equivalent is: db.tweets.update({system_classification: '+'}, {$set: {system_classification:'positive'}}, false, true) Parameter Description { system_classification: '+' } the first parameter identifies the documents to select { $set: { system_classification: 'positive' } } the second parameter is an operation ($set) and the parameter to that operation {system_classification: ‘positive’} false the third parameter indicates if this is a regular update or an upsert (true for upsert) true the final parameter indicates if the operation should be applied to all selected documents (or just the first)

  • How to market yourself as a software developer?

    - by karlphillip
    I have noticed that this is a frequent issue among younglings from technical areas such as ours. In the beginning of our careers we simply don't know how to sell ourselves to our employers, and random guy #57 (who is a programmer, but not as good as you - technically) ends up getting a raise/promotion just because he knows how to communicate and market himself better than you. Many have probably seen this happen in the past, and most certainly many more will in the future. What kind of skill/ability (either technical, or of other nature) do you think is relevant to point out when doing a job interview or asking for a raise, besides listing all the programming languages and libraries you know?
