  • Conference networking for the socially awkward

    - by Melanie Townsend
    Do you approach a room full of strangers with excitement at all the new people you’re going to chat to over coffee and a muffin as you swap tales of how you convinced your manager to give you the day “off”? Or, do you find rooms full of strangers intimidating and begin by scouting out a place you can stand quietly and not be in someone’s way until the next session begins? If you’re on the train to extrovert city, that’s great, well done, move along. If, on the other hand, a room full of strangers who all seem to inexplicably know each other already is more challenge than opportunity, then making those connections with other professionals can be more difficult. So, here’s some advice, some gleaned from other things I’ve read online when trying to overcome my own discomfort in large groups (hopefully minus the infuriating condescension), others are just things I’ve found helpful over the years. Start small Smaller groups are less intimidating, and, now that you’ve taken the plunge to show up, it’s harder to remain inconspicuous. I find it’s easier to speak to new people once the option NOT to has been taken away. You’re there now, smile through the awkward and you’ll be forever grateful when the three people you’ve met and gotten to know here are also at that gigantic conference later on (ideally, introducing you to other people). Smile, or at the very least, stop scowling You probably don’t even know you’re doing it. If your resting face doesn’t come across as manically happy, tinge that with some social anxiety and you become one great ball of unapproachable. Normally, I wouldn’t suggest this as a problem that needs fixing, I have personally honed this face to use while travelling alone all the time. However, if you are indeed hoping to meet some useful people and get the most out of this conference, you may need to remind yourself to smile. Prepare some ice breakers This is going to sound stupid, like “no one does this right?” stupid, but, just, trust me a minute. It’s okay to prepare. You don’t need to write word-for-word questions to ask people and practice them in a mirror – that would be strange. I’m suggesting to just have an arsenal of questions to ask people if you get stuck, what session has been your favorite, which ones are you most looking forward to, have you heard X presenter speak before, what did you think of them? Even just thinking about these things in advance can help, and, as a bonus, while the other person is answering it gives you a moment to tamp down that panic, I mean breathe, I mean get to know them. You’re not alone (in the least creepy way possible) See that person in the corner clutching their phone with a mild deer in the headlights look?  That is potentially your new conference buddy. Starting with something along the lines of: I don’t know about you, the sessions here are great but I find the crowds a little tough to deal with. Mind if I park here for a second? is a decent opener. Just walking around and looking at exhibitors (if applicable) is fine, but it’s a little too easy to wander about and not actually speak to anyone if that’s all you’re doing. If joining a group of people talking is too much to start with, one-on-one can be easier. Have goals Are there people in particular you wanted to speak to? Did you have a personal goal of speaking to at least “x” new people? Are you trying to get a contact in a specific company because you want to work with them on something? Does the business have vague goals as well that you may or may not be judged on later? Making specific goals you can accomplish lets you know whether you’ve actually succeeded in your “networking pursuits” or what you need to work on more for next time. Everyone’s got their own coping technique. Some people are able to remind themselves that “humans are fundamentally social creatures” and somehow that helps them, others drink which is not really something I recommend for professional conferences but to each their own, and some focus on the fact that networking can play a big role in their career path. Just do what works for you, and if there’re any tricks you’ve found helpful over the years, please share em.

  • If not now, then when?

    - by Chris Gardner
    Originally posted on: http://geekswithblogs.net/freestylecoding/archive/2013/10/25/if-not-now-then-when.aspx The time has been flying by this year. It seems like only yesterday that I mentioned the gorillagator, a simple construct of confusion to try to draw attention to my message. In reality, that message was sent over a month ago. During that time, the hours slipped to days and days to weeks. Many exciting things have happened to myself; I'm sure many exciting things have happened to you. I'm also sure that many terrifying things have happened to children and their families. 62 children enter treatment at a Children's Miracle Network Hospital every minute. That's nearly 60,000 children since I sent the last email. To put that number in perspective, that is more than the population of Greenland. If we expand that to the past year, they have been nearly 550,000 children treated. That is almost the population of Huntsville, Decatur, and all their suburbs combined. Over the past 4 years, I have raised a little more than $3,000 for Children's Hospital of Alabama. As a result, I received a call from the organizers of Extra Life thanking me for my dedicated work and informing me that I was the top supporters for Children's Hospital of Alabama ... with my measly three grand. We can do much better than that. It may sound like I'm trying to have fun by playing games for 24 hours. It is more than that. It is me using my time and body as a catalyst. It is me putting my passion to work for a cause. It is me turning my love into something tangible. I have been campaigning and fighting to give these children a chance for years. I have been asking you to help me support these children and families. I've been putting in countless hours of talking to people, impassioned emails, and carefully constructed tweets. I have been fighting with cutting edge, and sometimes expensive, technology to try to provide live streams of my marathons. I yearly put my body through 24 (and, this year, 25) hours of no sleep. I do this to represent the countless hours these families sit awake at their children's side. All I ask is a few minutes on a website and a few dollars. These few minutes and few dollars go a long way help people that are experiencing circumstances that only occur in our nightmares. I also ask that you take one extra step. Forward this plea to those that you know. I can only reach a small fraction of a percentage of the people that may be able to help. Together, we can reach the world. I raise money for Children's Hospital of Alabama. As this message branches out, people may wish to support a hospital closer to their area. I have included a link to the list of people that have dedicated their time and have received no donations. Find someone on the list supporting your local hospital and give them a donation. Let them know that their time and effort are appreciated. Together, we can do something great. Together, we can make a difference. Together, we all stand tall. Thank you. You can get more information at http://www.extra-life.org and http://childrensmiraclenetworkhospitals.org/" My donation page is http://www.extra-life.org/participant/cgardner The list of participants without donations is http://www.extra-life.org/index.cfm?fuseaction=donorDrive.eventParticipantList&page=629&eventID=512

  • Removing Barriers to Create Effective Data Models

    After years of creating and maintaining data models, I have started to notice common barriers that decrease the accuracy and usefulness of models. In my opinion, the main causes of these barriers are the lack of knowledge and communication from within a company. The lack of knowledge in regards to data models or data modeling can take many forms. Company Culture Knowledge Whether documented or undocumented, existing business rules of a company can affect how data is modeled. For example, if a company only allows 1 assigned person per customer to be able to manipulate a customer’s record then then a data model that includes an associated table that joins customers and employee’s would be unneeded because that would allow for the possibility of multiple employees to handle a customer because of the potential for a many to many relationship between Customers and Employees. Technical Knowledge Depending on the data modeler’s proficiency in modeling data they can inadvertently cause issues and/or complications with a design without even noticing. It is important that companies share data modeling responsibilities so that the models are developed from multiple perspectives of a system, company and the original problem.  In addition, the tools that a company selects to create data models can also affect the accuracy of the model if designer are not familiar with the tools or the tools are too complex to use for the designer. Existing System Knowledge In order for a data modeler to model data for an existing system so that new changes can be applied to a system then they need to at least know the basic concepts of a system so that they can work within it. This will promote reusability of data and prevent the chance of duplicating data. Project Knowledge This should be pretty obvious, but it is very hard to create an accurate data model without knowing what data needs to be modeled. I have always found it strange that I have been asked to start modeling data prior to a client formalizing any requirements. Usually when this happens I have to make several iterations to a model, and the client still does not know exactly what they want.  In addition additional issues can arise when certain stakeholders of a project are not consulted prior to the design or after the project is over because it can cause miss understandings and confusion by the end user as well as possibly not solving the original problem for which a project is intended to solve. One common thread between each type of knowledge is that they can all be avoided through the use of good communication. For example, if a modeler is new to a company then they should ask older employees about any business specific rules that may be documented or undocumented that must be applied to projects in general. Furthermore, if a modeler is not really familiar with a specific data modeling software then they need to speak up and ask for help form other employees or their manager. This will not only help the modeler in the project, but also help them in future projects that they do for the company. Additionally, if a project is not clearly defined prior to a data modeler being assigned the modeling project then it is their responsibility to communicate with the other stakeholders to clarify any part of a project that is unclear so that the data model that is created is accurately aligned with a project.

  • AccelerometerInput XNA GameComponent

    - by Michael B. McLaughlin
    Bad accelerometer controls kill otherwise good games. I decided to try to do something about it. So I create an XNA GameComponent called AccelerometerInput. It’s still a beta project but you are welcome to try it, use it, modify it, etc. I’m releasing under the terms of the Microsoft Public License. Important info: First, it only supports tilt-style controls currently. I have not implemented motion-style controls yet (and make no promises as to when I might find time to do so). Second, I commented it heavily so that you can (hopefully) understand what it is doing. Please read the comments and examine the sample game for a usage overview. There are configurable parameters which I encourage you to make use of (both by modifying the default values where your testing shows it to be appropriate and also by implementing a calibration mechanism in your game that lets the user adjust those configurable values based on his or her own circumstances). Third, even with this code, accelerometer controls are still a fairly advanced topic area; you will likely find nothing but disappointment if you simply plunk this into some project without testing it on a device (or preferably on several devices). Fourth, if you do try this code and find that something doesn’t work as expected on your phone, please let me know as I want to improve it and can only do so with your help. Let me know what phone model it is, what you tried doing, what you expected, and what result you had instead. I may or may not be able to incorporate it into the code, but I can let others know at the very least so that they can make appropriate modifications to their games (I’m hopeful that all phones are reasonably similar in their workings and require, at most, a slight calibration change, but I simply don’t know). Fifth, although I’ll do my best to answer any questions you may have about it, I’m very busy with a number of things currently so it might take a little while. Please look through the code and examine the comments and sample game first before asking any questions. It’s likely that the answer is in there. If not, or if you just aren’t really sure, ask away. Sixth, there are differences between a portrait-mode game and a landscape mode game (specifically in the appropriate default tilt adjustment for toward the user/away from the user calculations). This is documented and the default is set for landscape. If you use this for a portrait game, make the appropriate change (look for the TODO: comment in AccelerometerInput.cs). Seventh, no provision whatsoever is made for disabling screen locking. It is up to you to implement that and to take appropriate measures to detect when the user has been idle for too long and timeout the game. That code is very game-specific. If you have questions about such matters, consult the relevant MSDN documentation and, if you still have questions, visit the App Hub forums and ask there. I answer questions there a lot and so I may even stumble across your question and answer it. But that’s a much better forum than the comments section here for questions of that sort so I would appreciate it if you asked idle detection-related questions there (or on some other suitable site that you may be more familiar and comfortable with). Eighth, this is an XNA GameComponent intended for XNA-based games on WP7. A sufficiently knowledgeable Silverlight developer should have no problem adapting it for use in a Silverlight game or app. I may create a Silverlight version at some point myself. Right now I do not have the time, unfortunately. Ok. Without further ado: http://www.bobtacoindustries.com/developers/utils/AccelerometerInput.zip Have a great St. Patrick’s Day!

  • Games development with a game loop that's abstracted away

    - by Davy8
    Most game development happens with a main game loop. Are there any good articles/blog posts/discussions about games without a game loop? I imagine they'd mostly be web games, but I'd be interested in hearing otherwise. (As a side note, I think it's really interesting that the concept is almost exclusively used in gaming as far as I'm aware, perhaps that may be another question.) Edit: I realize there's probably a redraw loop somewhere. I guess what I really mean is a loop that is hidden to you. Frames are something you as the developer are not concerned with as you're working on a higher level of abstraction. E.g. someLootItem.moveTo(inventory, someAnimatationType) and that will move from the loot box to your inventory using the specified animation type without the game developer having to worry about the implementation details of that animation. Maybe that's how "real" games end up working, but from reading most tutorials they seem to imply a much more granular level of control is used, but that might just be an artifact of being a tutorial. Edit2: I think most people are misunderstanding what I'm trying to ask, likely because I'm having trouble describing exactly what I'm trying to ask. After some more thinking perhaps what I'm referring to is more along the lines of what I believe is referred to as "scripting" where you're working at a very high level and having some game engine take care of the low level details. For example, take custom maps in Starcraft II or Warcraft III. Many of the "maps" have gameplay that deviates enough from the primary game that they could be considered a separate game written on the same engine. What I'm referring to then is along those lines. I may be wrong because I only dabbed in the Warcraft III editor, but as far as I remember no where in the map editor do you control the game loop, and yet you can create many different games out of it. In my mind, these are games in their own right. If you're playing DotA you don't say you're playing Warcraft III, you say you're playing DotA because that's the actual game you're playing. Such a system may impose limitations that don't exist if you're creating a game from scratch, but it greatly reduces development time because much of the "hard" work has already been done for you. Hopefully that clarifies what I'm asking. Another example of what is I mean, is when you write a web app, of course it communicates through sockets and TCP. But does the average web developer doesn't explicitly write code for connecting sockets. They just need to know about receiving a request and sending a response. There are unique scenarios where you do occasionally need to use raw sockets, but it's generally rare in web development. In a similar fashion, it's very possible to write a game without directly using the game loop, even though one is used behind the scenes. Probably not a AAA title, but there must be hundreds of smaller scale games that can and possibly are written this way. Are there any good resources on writing these "simpler" games?

  • Attending a Career Fair: &ldquo;Don&rsquo;t be shy &ndash; Be prepared&rdquo;

    - by jessica.ebbelaar
    There are a large number of ways to interact with companies nowadays. The career fair is a very effective and personal way to interact with a number of different companies in a very short period of time. Here are some simple tips to help you perform during a career fair. Do research The key to being successful at a career fair is to do research before you go. Make a first selection of the companies you feel could be interesting for you. Include many types of employers. Once you have decided on the list of companies you want to visit, go to their career portal. Inform yourself about what the company does, i.e what roles there are available, how the company culture is described, what impression the testimonials give you. The question that you still have after reviewing this information, are the ones you can discuss with the company on the fair. Sell yourself Visit the companies you have on your top 5 list first, so you will be at your highest energy level to make that first impression. Think in advance about what you are going to tell the recruiter. Prepare a 30-second introduction (including degree, strengths, skills & experience) Be confident when you talk about your experience. Remember to start the conversation with a smile, make good eye contact and give a firm handshake. You could be speaking to your next manager, so be professional! If you already know what jobs you are interested in, relate your skills and experience to the roles that the company has available. If you are not yet sure gather as much information as you can about employment and/or hiring procedures, specific skills necessary for different jobs, training and career paths. Stand out As career fairs are very crowded and the attending companies meet with a lot of potential candidates on one day, you have to make sure you are noticed in a positive way. A good preparation and asking questions that show you have a good understanding of the industry, organization and roles will help you. Be aware of time demands on employers. Do not monopolize an employer's time. Dress appropriately to make a good first impression. Bring your resume Do not forget to bring your resume in print or on a USB-stick to the fair. If you are searching for different types of jobs, bring different versions of your resume. Your resume should be short and professional on white paper that is free of graphics or fancy print styles and containing larger margins for interviewer notes. Follow up After each conversation ask who you can contact for follow-up discussions about the specific roles. Use the back of a business card to record notes that help you remember important details and follow-up instructions. If no card is available, record the contact information and your comments in your notepad or phone. Last but not least, thank everyone you talk to for their time. Follow up as soon as possible with thank you notes that address the companies’ hiring needs, your qualifications, and express your desire for a second interview. What not to do… Do not visit a company with a group of friends. Interact with the companies on your own, to make your own positive impression. Do not walk up to a recruiter and interrupt a current conversation; wait your turn and be polite. What you should absolutely avoid is a grab and run on freebies! Take the time to speak to the company and ask for a freebie at the end of the conversation in case they are not offered to you. Good luck with the preparations for the career fair you will attend. Oracle recruiters look forward to meet you! They will be present on a large number of fairs in the region. For an overview of the fairs go to the Events & Calendar page on http://campus.oracle.com If you have any questions related to this article feel free to contact [email protected].

  • Help Me Help You Fix That

    - by BuckWoody
    If you've been redirected here because you posted on a forum, or asked a question in an e-mail, the person wanted you to know how to get help quickly from a group of folks who are willing to do so - but whose time is valuable. You need to put a little effort into the question first to get others to assist. This is how to do that. It will only take you a moment to read... 1. State the problem succinctly in the title When an e-mail thread starts, or a forum post is the "head" of the conversation, you'll attract more helpers by using a descriptive headline than a vague one. This: "Driver for Epson Line Printer Not Installing on Operating System XYZ" Not this: "Can't print - PLEASE HELP" 2. Explain the Error Completely Make sure you include all pertinent information in the request. More information is better, there's almost no way to add too much data to the discussion. What you were doing, what happened, what you saw, the error message, visuals, screen shots, whatever you can include. This: "I'm getting error '5203 - Driver not compatible with Operating System since about 25 years ago' in a message box on the screen when I tried to run the SETUP.COM file from my older computer. It was a 1995 Compaq Proliant and worked correctly there.." Not this: "I get an error message in a box. It won't install." 3. Explain what you have done to research the problem If the first thing you do is ask a question without doing any research, you're lazy, and no one wants to help you. Using one of the many fine search engines you can most always find the answer to your problem. Sometimes you can't. Do yourself a favor - open a notepad app, and paste the URL's as you look them up. If you get your answer, don't save the note. If you don't get an answer, send the list along with the problem. It will show that you've tried, and also keep people from sending you links that you've already checked. This: "I read the fine manual, and it doesn't mention Operating System XYZ for some reason. Also, I checked the following links, but the instructions there didn't fix the problem: " Not this: <NULL> 4. Say "Please" and "Thank You" Remember, you're asking for help. No one owes you their valuable time. Ask politely, don't pester, endure the people who are rude to you, and when your question is answered, respond back to the thread or e-mail with a thank you to close it out. It helps others that have your same problem know that this is the correct answer. This: "I could really use some help here - if you have any pointers or things to try, I'd appreciate it." Not this: "I really need this done right now - why are there no responses?" This: "Thanks for those responses - that last one did the trick. Turns out I needed a new printer anyway, didn't realize they were so inexpensive now." Not this: <NULL> There are a lot of motivated people that will help you. Help them do that.

  • Top 5 characteristics Recruiters are looking for

    - by Maria Sandu
    Of course many skills and characteristics recruiters are looking for are job specific. But whether you are a graduate fresh out of college or seasoned in the workplace, recruiters are also looking for generic skills and attitude to see whether you are a good fit to the company. So make sure you prepare and show through examples that you have these skills. 1. Drive/passion Liking the job you are applying for is paramount and something recruiters are always looking for. Show and prove your drive for the role and/or the field you are applying for. Always be prepared to pitch yourself, this shows your drive in the role you are applying for. 2. Communication skills People often make the mistake by thinking this skill is related to how good they are able to talk about their background and expertise. This is important, but as least as important is it that you listen well to questions that are asked. Make sure you answer to the point and ask questions if you want questions to be clarified. This shows your interest in the role and the ability to communicate clearly. This also helps you building trust with the recruiter every time you speak to him/her. 3. Confidence Recruiters are looking for the best candidate for the job. So if you don’t think you are the best candidate why should the recruiter? Show with confidence, without being arrogant (think about building trust), why you are the right person for the job. Confidence also shows in your answers to difficult questions. Be confident enough to explain why some experiences went wrong and how you learnt from them. If you don’t have a direct explanation on a question, it is better to ask for a second to think instead of a random answer. 4. Vision The main reason to hire graduates for many companies is that graduates are perceived to be flexible. The organisation will train and up skill you in the direction best suitable for the organisation. However the most intense learning path is realised when you also know where you want to go. Companies are often happy to accommodate you to support with training and development, but if you don’t have a clear vision on what you want to achieve for yourself and what value you bring to the company, recruiters can decide you are not the right candidate as they are afraid you aren’t going to stay in the company. 5. Business awareness For every job you apply you will get challenged on your knowledge and interest for the market and business they are in. All companies add value in different ways in their respective markets. So make sure you are aware of what a company is doing, what their goal is and why and how they exist and how you can add value for the company in the role you are applying for. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin-top:0cm; mso-para-margin-right:0cm; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0cm; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

  • Why Are We Here?

    - by Jonathan Mills
    Back in the early 2000s, Toyota had a vision of building the number one best selling minivan in North America. Their current minivan, the Sienna, was small, underpowered, and badly needed help.  Yuji Yokoya was given the job of re-engineering the Sienna. There was just one problem, Yuji, lived in Japan. He did not know the people or places that he would be engineering for. Believe it or not, Japan is nothing like North America. So, what does a chief engineer do in a situation like that? He packed up his team and flew halfway around the world. He made a commitment to drive through every state in the US, every province in Canada, and Mexico. He met the people and drove the roads that the Sienna would be driving. And guess what, what he learned on that trip revolutionized the Sienna. The innovations he made, sent the Sienna to number one. Why? Because he knew who he was building his product for. He knew, why he was there.Let me ask you this, do you know why you are building what you are building? As a member of a product team, can you tell me how your product will be used in the real world? As you are writing code, building test plans, writing stories, or any of the other project tasks, can you picture the face of a person who will be using what you are building? All to often, the answer to those questions is, no. Why is it important? Because, every day, project team members make assumptions. Over a given project, it is safe to say project team members will make thousands of assumptions about what they are doing. And all to often, those assumptions are not quite right. Its not that they are not good at their job, its just that they don’t really know why they are there.So, what to do? First and foremost, stop doing what you are doing. Yes, really. Schedule some time to go visit the people who will be using your product. Don’t invite them to you, go to them. Watch them work. Interact with them. Ask them questions. Maybe even try it out yourself. This serves two purposes. One, It shows them that you care about them. They will be far more engaged in your project if they feel like you care. And nothing says you care more that spending some time. Second, if gives you the proper frame of reference for you work. It gives you something tangible to go back to as you are building your product. As you make the thousands of assumptions that you will make over the life of your project, it gives you something to see in your mind that makes it real to you.Ultimately, setting a proper frame of reference is critical to the overall success of a project. The funny thing is, it really does not even take that long. In most cases, a 2-3 hour session will give you most of what you need to get the right insight. For the project, it will be the best 2 hours you could spend.

  • Get More From Your Service Request

    - by Get Proactive Customer Adoption Team
    Leveraging Service Request Best Practices Use best practices to get there faster. In the daily conversations I have with customers, they sometimes express frustration over their Service Requests. They often feel powerless to make needed changes, so their sense of frustration grows. To help you avoid some of the frustration you might feel in dealing with your Service Requests (SR), here are a few pointers that come from our best practice discussions. Be proactive. If you can anticipate some of the questions that Support will ask, or the information they may need, try to provide this up front, when you log the SR. This could be output from the Remote Diagnostic Agent (RDA), if this is a database issue, or the output from another diagnostic tool, if you’re an EBS customer. Any information you can supply that helps us understand the situation better, helps us resolve the issue sooner. As you use some of these tools proactively, you might even find the solution to the problem before you log an SR! Be right. Make sure you have the correct severity level. Since you select the initial severity level, it’s easy to accept the default without considering how significant this may be. Business impact is the driving factor, so make sure you take a moment to select the severity level that is appropriate to the situation. Also, make sure you ask us to change the severity level, should the situation dictate. Be responsive! If this is an important issue to you, quickly follow up on any action plan submitted to you by Oracle Support. The support engineer assigned to your Service Request will be able to move the issue forward more aggressively when they have the needed information. This is crucial in resolving your issues in a timely manner. Be thorough. If there are five questions in the action plan, make sure you provide an answer for all five questions in one response, rather than trickling them in one at a time. This will allow the engineer to look at all of the information as a whole and to avoid multiple trips to your SR, saving valuable time and getting you a resolution sooner. Be your own advocate! You know your situation best; make sure Oracle Support understands both how and why this issue is important to you and your company. Use the escalation process if you're concerned that your SR isn't going the right direction, the right pace, or through the right person. Don't wait until you're frustrated and angry. An escalation is as simple as a quick conversation on the phone and can be amazingly effective in getting your issues back on track. The support manager you speak with is empowered to make any needed changes. Be our partner. You can make your support experience better. When your SR has been resolved, you may receive a survey request. This is intended to get your feedback about how your SR went and what we can do to improve your overall support experience. Oracle Support is here to help you. Our goal with any Service Request is to provide the best possible solution as quickly as possible. With your help, we’ll be able to do this with your Service Request too.

  • Getting Started with Cloud Computing

    - by juanlarios
    You’ve likely heard about how Office 365 and Windows Intune are great applications to get you started with Cloud Computing. Many of you emailed me asking for more info on what Cloud Computing is, including the distinction between "Public Cloud" and "Private Cloud". I want to address these questions and help you get started. Let's begin with a brief set of definitions and some places to find more info; however, an excellent place where you can always learn more about Cloud Computing is the Microsoft Virtual Academy. Public Cloud computing means that the infrastructure to run and manage the applications users are taking advantage of is run by someone else and not you. In other words, you do not buy the hardware or software to run your email or other services being used in your organization – that is done by someone else. Users simply connect to these services from their computers and you pay a monthly subscription fee for each user that is taking advantage of the service. Examples of Public Cloud services include Office 365, Windows Intune, Microsoft Dynamics CRM Online, Hotmail, and others. Private Cloud computing generally means that the hardware and software to run services used by your organization is run on your premises, with the ability for business groups to self-provision the services they need based on rules established by the IT department. Generally, Private Cloud implementations today are found in larger organizations but they are also viable for small and medium-sized businesses since they generally allow an automation of services and reduction in IT workloads when properly implemented. Having the right management tools, like System Center 2012, to implement and operate Private Cloud is important in order to be successful. So – how do you get started? The first step is to determine what makes the most sense to your organization. The nice thing is that you do not need to pick Public or Private Cloud – you can use elements of both where it makes sense for your business – the choice is yours. When you are ready to try and purchase Public Cloud technologies, the Microsoft Volume Licensing web site is a good place to find links to each of the online services. In particular, if you are interested in a trial for each service, you can visit the following pages: Office 365, CRM Online, Windows Intune, and Windows Azure. For Private Cloud technologies, start with some of the courses on Microsoft Virtual Academy and then download and install the Microsoft Private Cloud technologies including Windows Server 2008 R2 Hyper-V and System Center 2012 in your own environment and take it for a spin. Also, keep up to date with the Canadian IT Pro blog to learn about events Microsoft is delivering such as the IT Virtualization Boot Camps and more to get you started with these technologies hands on. Finally, I want to ask for your help to allow the team at Microsoft to continue to provide you what you need. Twice a year through something we call "The Global Relationship Study" – they reach out and contact you to see how they're doing and what Microsoft could do better. If you get an email from "Microsoft Feedback" with the subject line "Help Microsoft Focus on Customers and Partners" between March 5th and April 13th, please take a little time to tell them what you think.

  • PCI Encryption Key Management

    - by Unicorn Bob
    (Full disclosure: I'm already an active participant here and at StackOverflow, but for reasons that should hopefully be obvious, I'm choosing to ask this particular question anonymously). I currently work for a small software shop that produces software that's sold commercially to manage small- to mid-size business in a couple of fairly specialized industries. Because these industries are customer-facing, a large portion of the software is related to storing and managing customer information. In particular, the storage (and securing) of customer credit card information. With that, of course, comes PCI compliance. To make a long story short, I'm left with a couple of questions about why certain things were done the way they were, and I'm unfortunately without much of a resource at the moment. This is a very small shop (I report directly to the owner, as does the only other full-time employee), and the owner doesn't have an answer to these questions, and the previous developer is...err...unavailable. Issue 1: Periodic Re-encryption As of now, the software prompts the user to do a wholesale re-encryption of all of the sensitive information in the database (basically credit card numbers and user passwords) if either of these conditions is true: There are any NON-encrypted pieces of sensitive information in the database (added through a manual database statement instead of through the business object, for example). This should not happen during the ordinary use of the software. The current key has been in use for more than a particular period of time. I believe it's 12 months, but I'm not certain of that. The point here is that the key "expires". This is my first foray into commercial solution development that deals with PCI, so I am unfortunately uneducated on the practices involved. Is there some aspect of PCI compliance that mandates (or even just strongly recommends) periodic key updating? This isn't a huge issue for me other than I don't currently have a good explanation to give to end users if they ask why they are being prompted to run it. Question 1: Is the concept of key expiration standard, and, if so, is that simply industry-standard or an element of PCI? Issue 2: Key Storage Here's my real issue...the encryption key is stored in the database, just obfuscated. The key is padded on the left and right with a few garbage bytes and some bits are twiddled, but fundamentally there's nothing stopping an enterprising person from examining our (dotfuscated) code, determining the pattern used to turn the stored key into the real key, then using that key to run amok. This seems like a horrible practice to me, but I want to make sure that this isn't just one of those "grin and bear it" practices that people in this industry have taken to. I have developed an alternative approach that would prevent such an attack, but I'm just looking for a sanity check here. Question 2: Is this method of key storage--namely storing the key in the database using an obfuscation method that exists in client code--normal or crazy? Believe me, I know that free advice is worth every penny that I've paid for it, nobody here is an attorney (or at least isn't offering legal advice), caveat emptor, etc. etc., but I'm looking for any input that you all can provide. Thank you in advance!

  • How much am I worth hourly as a software/web developer? [closed]

    - by luckysmack
    I may be starting a new job very soon as a developer for both web and desktop software. The primary languages I will be using is ASP.NET with C# with some php for existing projects(I've already had one interview which went very well). The job deals primarily in advertising. But this is my first real job in the market, I have no degrees, but have some college time(~1yr). So I am primarily self taught. They are fully aware of my skill set and lack of degrees or certificates. I applied as an entry level developer. It will be a permanent and full time/hourly position, and not a per contract job. So since it my cherry job, im not really sure what to ask for. even though im self taught im pretty confident in my skills and know what im doing fairly well. I pick up on new concepts very well and find new things fairly easy to learn. Here is a very brief summary of my skills: PHP: ~2years C#/.NET: 2 months Python: Basics only. ~1 month OOP Familiarity: Great (1 year) MVC Familiarity: Great (1 year) PHP Frameworks used: CakePHP(6 months), Yii(3 months), Lithium(3 months) CMS Familiar with: Drupal(1.5 years), Wordpress(only basics) I also have ~2yrs experience in maintaining my own VPS server and the hassles all that entails (linux/debian) Pretty much all the above will be used at this job. Although I will be using C# a vast majority of the time. I only recently started learning it but am moving along fairly rapidly and its all going smooth as butter. So what have I built? I have one proprietary site built in drupal which is used an an order log for products, inventory, and their shipments. It is also able to process payments through paypal merchant services. I have worked on a handful of other small apps used here and there I'm not able to show but which worked fairly well (all in php using frameworks though). The business does fairly well and is far from a a typical corporate type environment. It is much closer to a small development studio. And it is based out of northern California. I don't know how/what more info I can give on them. I also want this to be able to be referenced by other people possibly so I am looking for general tips and ideas to get an answer as well. I had trouble finding a reasonable range on other websites which seemed to be either way to low, or showed what a veteran developer makes. I know this is a fairly subjective question, but it is difficult to get a reasonable answer or guesstimate anywhere else. Even if only a little bit help, its much appreciated. So as for the direct question, based on all this info (did I miss anything?), how much should I ask for hourly? How much am I worth as a software developer?

  • A simple augmented reality application in C#

    - by Ian
    Hi All, I would like to start a personal project that will give me a lot of new concept to learn and understand. After some thought, I figured that an Augmented Reality related project will be the most beneficial for me because of the following reasons: I haven't tried interfacing a program with a live video/camera feed I haven't done any "image processing" project I haven't done any "graphics rendering" ever With that said, you can assume that I will totally suck at AR. So I'm here to ask for some advice regarding the best way to go through this. st milestone project that I am thinking of is to take a cheap webcam and read some Data Matrix using C#. nd milestone project will render some text-overlay on the feed when presented with a certain Data Matrix. rd milestone project will actually render some 3D shapes. I've searched all-around and found some nice yet advanced materials for AR: http://sites.google.com/site/augmentedrealitytestingsite/ http://soldeveloper.com/ http://www.mperfect.net/wpfAugReal/ So I came here to ask the following: Do you think my milestone is reasonable given my "deficiencies"? In order to start Milestone 1, can you give some materials that I can study? I prefer online materials. Thanks!

  • Keyboard Animation Issues When Calling becomeFirstResponder within a Modal View Controller

    - by LucasTizma
    I've been having some issues with calling -becomeFirstResponder on a UITextField contained with a view controller that is presented modally. I call this method in the modal view controller's -viewDidLoad method so that the keyboard is immediately displayed. What I expected is for both the keyboard and the modal view controller to animate from up the bottom of the screen at the same time. However, what I'm observing is the following: There is a ~0.2 second UI lag between clicking the button that calls the -presentModalViewController:animated: method on the parent view controller and when the child view controller begins to animate modally. The keyboard is immediately presented with absolutely no animation about half-way through the modal view controller's animation. Once the modal view controller's animation is complete, everything else seems to operate smoothly. Dismissing the modal view controller results in it being smoothly animated off screen (along with the keyboard, coincidentally). It's as if the keyboard's animation and the modal view controller's animation are both competing for some lower-level Core Animation resource at the same time, but I don't see why this should be happening. What further seems to corroborate this hunch is if I don't ask the UITextField to become the first responder (i.e., if I don't ask the keyboard to present itself), then there is absolutely no UI lag, and the modal view controller animates instantly. Interestingly, if I do something like [self.textField performSelector:@selector(becomeFirstResponder) withObject:nil afterDelay:0.0001]; then the animation of the keyboard happens nearly at the same time as the modal view controller's animation -- it's extremely difficult to tell that they aren't both being animated at the exact same time. Furthermore, there's no more UI lag. Has anyone experienced anything similar to this?

  • How to weed out the bad programmers from the competent ones in the interview process

    - by thaBadDawg
    I am getting ready to add another developer to my team and I want to try and fix the mistakes I made in my last hiring cycle. I like to think of myself as a competent programmer (I can be given a project, I can deliver on that project and the deliverable work with very few if any bugs) and so I ask questions that I would ask myself in an interview. I've come to the conclusion that my interviewing skills are completely lacking because the last two people I've hired interviewed incredibly well but have been less than ideal at the tasks that they've been given. My CTO (who was completely useless in giving any guidance as to how) suggested I improve on my interviewing skills. The question is this - How does one programmer interview another programmer and get an understanding of the other programmer's abilities? Edit: Though slightly different, the answers provided to this question could be of use to you. That question concerns specific interview questions while yours seems to be more general about interview approaches and not just about the questions themselves. Update: Just for the hell of it I asked two of the guys I worked with if they could do FizzBuzz. 45 minutes and 80 minutes to work it out. And these aren't bottom level guys either.

  • Need help figuring out an appropriate job title

    - by Programmer
    My official title is Programmer but I do not feel it fully represents what I do because a large portion of my time is spent working with QA on testing, acting as a liason with our offshore development team and meeting with business managers to help make decisions about new features. My understanding has always been that the title "Programmer" is usually applied to someone who simply writes code, not someone who is involved in architecture decisions or managerial issues related to offshore teams. It is true that I do not have any budgeting duties as my manager does and I do not deal with contracts related to the offshore development. My manager handles both of those duties. But the title "Programmer" seems like a very narrow label for the broad range of responsibilities that I have. For example, I sometimes help QA staff to figure out how to do their testing. And I give the offshore team detailed instructions about how to implement new features - I review their code and integrate their changes locally. I don't know if this is typical these days or if I should ask for a title change. If I should ask for a title change, I would appreciate any recommendations.

  • Should UTF-16 be considered harmful?

    - by Artyom
    I'm going to ask what is probably quite a controversial question: "Should one of the most popular encodings, UTF-16, be considered harmful?" Why do I ask this question? How many programmers are aware of the fact that UTF-16 is actually a variable length encoding? By this I mean that there are code points that, represented as surrogate pairs, take more then one element. I know; lots of applications, frameworks and APIs use UTF-16, such as Java's String, C#'s String, Win32 APIs, Qt GUI libraries, the ICU Unicode library, etc. However, with all of that, there are lots of basic bugs in the processing of characters out of BMP (characters that should be encoded using two UTF-16 elements). For example, try to edit one of these characters: 𝄞 𝕥 𝟶 𠂊 You may miss some, depending on what fonts you have installed. These characters are all outside of the BMP (Basic Multilingual Plane). If you cannot see these characters, you can also try looking at them in the Unicode Character reference. For example, try to create file names in Windows that include these characters; try to delete these characters with a "backspace" to see how they behave in different applications that use UTF-16. I did some tests and the results are quite bad: Opera has problem with editing them Notepad can't deal with them correctly (delete for example) File names editing in Window dialogs in broken All QT3 applications can't deal with them. StackOverflow seems to remove these characters if edited directly in as Unicode characters, and only seems to allow them as HTML Unicode escapes. So... This was very simple test. Do you think that UTF-16 should be considered harmful?

  • Some general C questions.

    - by b-gen-jack-o-neill
    Hello. I am trying to fully understand the process pro writing code in some language to execution by OS. In my case, the language would be C and the OS would be Windows. So far, I read many different articles, but I am not sure, whether I understand the process right, and I would like to ask you if you know some good articles on some subjects I couldn´t find. So, what I think I know about C (and basically other languages): C compiler itself handles only data types, basic math operations, pointers operations, and work with functions. By work with functions I mean how to pass argument to it, and how to get output from function. During compilation, function call is replaced by passing arguments to stack, and than if function is not inline, its call is replaced by some symbol for linker. Linker than find the function definition, and replace the symbol to jump adress to that function (and of course than jump back to program). If the above is generally true and I get it right, where to final .exe file actually linker saves the functions? After the main() function? And what creates the .exe header? Compiler or Linker? Now, additional capabilities of C, today known as C standart library is set of functions and the declarations of them, that other programmers wrote to extend and simplify use of C language. But these functions like printf() were (or could be?) written in different language, or assembler. And there comes my next question, can be, for example printf() function be written in pure C without use of assembler? I know this is quite big question, but I just mostly want to know, wheather I am right or not. And trust me, I read a lots of articles on the web, and I would not ask you, If I could find these infromation together on one place, in one article. Insted I must piece by piece gather informations, so I am not sure if I am right. Thanks.

  • detecting pauses in a spoken word audio file using pymad, pcm, vad, etc

    - by james
    First I am going to broadly state what I'm trying to do and ask for advice. Then I will explain my current approach and ask for answers to my current problems. Problem I have an MP3 file of a person speaking. I'd like to split it up into segments roughly corresponding to a sentence or phrase. (I'd do it manually, but we are talking hours of data.) If you have advice on how to do this programatically or for some existing utilities, I'd love to hear it. (I'm aware of voice activity detection and I've looked into it a bit, but I didn't see any freely available utilities.) Current Approach I thought the simplest thing would be to scan the MP3 at certain intervals and identify places where the average volume was below some threshold. Then I would use some existing utility to cut up the mp3 at those locations. I've been playing around with pymad and I believe that I've successfully extracted the PCM (pulse code modulation) data for each frame of the mp3. Now I am stuck because I can't really seem to wrap my head around how the PCM data translates to relative volume. I'm also aware of other complicating factors like multiple channels, big endian vs little, etc. Advice on how to map a group of pcm samples to relative volume would be key. Thanks!

As a very simple test, I inserted a value for 4 columns into the Keyspace1/Standard1 column family on my local machine amounting to about 100 bytes of data. Then I read it back as fast as I could by row key. I can read it back at 160,000/second. Great. Then I put in a million similar records all with keys in the form of X.Y where X in (1..10) and Y in (1..100,000) and I queried for a random record. Performance fell to 26,000 queries per second. This is still well above the number of queries we need to support (about 1,500/sec) Finally I put ten million records in from 1.1 up through 10.1000000 and randomly queried for one of the 10 million records. Performance is abysmal at 60 queries per second and my disk is thrashing around like crazy. I also verified that if I ask for a subset of the data, say the 1,000 records between 3,000,000 and 3,001,000, it returns slowly at first and then as they cache, it speeds right up to 20,000 queries per second and my disk stops going crazy. I've read all over that people are storing billions of records in Cassandra and fetching them at 5-6k per second, but I can't get anywhere near that with only 10mil records. Any idea what I'm doing wrong? Is there some setting I need to change from the defaults? I'm on an overclocked Core i7 box with 6gigs of ram so I don't think it's the machine. Here's my code to fetch records which I'm spawning into 8 threads to ask for one value from one column via row key: ColumnPath cp = new ColumnPath(); cp.Column_family = "Standard1"; cp.Column = utf8Encoding.GetBytes("site"); string key = (1+sRand.Next(9)) + "." + (1+sRand.Next(1000000)); ColumnOrSuperColumn logline = client.get("Keyspace1", key, cp, ConsistencyLevel.ONE); Thanks for any insights

  • How to get rid of the GUI access from shared library.

    - by Inso Reiges
    Hello, In my project i have a shared library with cross-platform code that provides a very convenient abstraction for a number of its clients. To be more specific, this library provides data access to encrypted files generated by main application on a number of platforms. There is a great deal of complicated code there that implements cryptographic protocols and as such is very error-prone and should be shared as much as possible across clients and platforms. However parsing all this encrypted stuff requires asking user for a number of different secrets ones in a while. The secret can be either a password, a number of shared passwords or a public key file and this list is a hot target for extension in the future. I can't really ask the user for any of those secrets beforehand from main application, because i really don't know what i need to ask for until i start working with the encrypted data directly in the library code. So i will have to create dialogs and call them from the library code. However i really see this as a bad idea, because (among other things) there is a possibility of a windows service using it and services can't have GUI access. The question is, are there any known ways or patterns to get rid of the GUI calls that are suitable for my case? Thank you.

  • Working for free

    - by truncate
    Finances are making me take an extended period off of my college education. In my current state, I don't feel fully qualified to be employed by an iPhone software company. While I work on getting things back together, I'd like to try an work for a software company for free in my local area (I'm going to college out of state and have to move back as well). The economy has forced employers to be very picky about who they hire, if any at all. Since I'd like to continue refining my abilities, I was wondering on what the consensus is on working for free. It can't be considered an internship, as I would no longer be in school..., I guess an apprenticeship is more appropriate. Like I said, I don't think I'm qualified to be paid for my services, and I don't want to be. I just don't know how to ask, or if it's even appropriate to ask them to show me how to develop software in the real world. My thinking is that they would be willing to get some work done for free and if I prove myself, they could hire me. If not, there was no major loss. They get some free development, and lose a bit of time helping show me the ropes. I get either a job, or valuable experience that I need. The other alternative is that I try to work out things by myself on the iPhone platform, but that sounds terrifying. I appreciate any input the community has to offer.
