  • IT Admin for Thrill Seekers

    - by Tony Davis
    A developer suggested to me recently that the life of the DBA was, surely, a dull one. My first reaction was indignation, but quickly followed by the thought that for many people excitement isn't necessarily the most desirable aspect of their job. It's true that some aspects of the DBA role seem guaranteed to quieten the pulse; in the days of tape backups, time must have slowed to eternity for the person whose job it was to oversee this process, placing tapes into secure containers, ensuring correct labeling, and.sorry, I drifted off there for a second. On the other hand, if you follow the adventures of the likes of Brent Ozar or Tom LaRock, you'd be forgiven for thinking that much of a database guy's time is spent, metaphorically, diving through plate glass windows in tight fitting underwear in order to extract grateful occupants from burning database applications. Alas it isn't true of the majority, but it isn't as dull as some people imagine, and is a helter-skelter ride compared with some other IT roles. Every IT department has people who toil away in shadowy corners doing quiet but mysterious tasks. When you ask them to explain what they do, you almost immediately want them to stop, but you hear enough to appreciate that these tasks are often absolutely vital to the smooth functioning of an IT organization. Compared with them, the DBAs are prima donnas. Here are a few nominations: Installation engineer - install all of the company's laptops and workstations, and software, deal with licensing, shipping and data entry.many organizations, especially those subject to tight regulation, would simply grind to a halt without their efforts. Localization engineer - Not quite software engineering, not quite translation, the job is to rebuild a product in a different language and make sure everything still works. QA Tester - firstly, I should say that the testers at Red Gate seem to me some of the most-fulfilled in the company. I refer here to the QA Tester whose job is more-or-less entirely to read a script, click some buttons and make sure the actual and expected values match. Configuration manager - for example, someone whose main job is to configure build environments so that devs can access their source code; assuredly necessary for the smooth functioning and productivity of the team, and hopefully well-paid. So what other sort of job in IT should one choose if the work of a DBA proves to be too exciting? Or are these roles secretly more exciting than many imagine? I invite you all to put forward your own suggestions. Cheers, Tony.

  • finding high end software contracting jobs

    - by numerical25
    I've been contracting for about 3 years now. I am currently a contractor for a web firm. This is a hourly position. I want to find larger projects. I had read that some people are able to only do one or two jobs a year and be set on that. I want those types of jobs, and I want to hire people to take on these jobs as well, but I have no idea where to start. I highly doubt places like odesk post these types of contracts. Where can I find them? How can I make good money and live comfortably while working for myself?

  • On the Road(Map)

    - by Valter Minute
    The new roadmap of Windows Embedded has been announced, this is great news for anyone that wants to use Windows Embedded technologies in her/his device. Roadmaps are usually stuff for marketing people, but as a technician is important to know that you are basing your product on a system that is going to be supported for some years and that you can evolve it and will not have to re-design it completely to change its OS (unless this proves to be more convenient, of course!). Here you can read the press release: http://www.microsoft.com/Presspass/Features/2011/nov11/11-14RoadMap.mspx and here Olivier Bloch’s summary (the part that should interest tech people): http://blogs.msdn.com/b/obloch/archive/2011/11/14/windows-embedded-roadmap-update.aspx

  • Learning MVC for a JSP Resource and ASP.Net WebForms Resource

    - by Lijo
    Statement from a colleque: - "People with ASP.Net WebForms skills should be able to learn it easily as the fundamental concept is same.” Consider two people –one from JSP background and other from ASP.Net WebForms background. Now both need to learn ASP.Net MVC in RAZOR. Do you think the person from ASP.Net Webforms background has significant advantage over the person from JSP background? My feeling is – it is equally difficult for JSP person and ASP.Net Webforms person to learn MVC with RAZOR. What is your take on it? Any statistics that you can provide for this?

  • 8 Reasons Why Even Microsoft Agrees the Windows Desktop is a Nightmare

    - by Chris Hoffman
    Let’s be honest: The Windows desktop is a mess. Sure, it’s extremely powerful and has a huge software library, but it’s not a good experience for average people. It’s not even a good experience for geeks, although we tolerate it. Even Microsoft agrees about this. Microsoft’s Surface tablets with Windows RT don’t support any third-party desktop apps. They consider this a feature — users can’t install malware and other desktop junk, so the system will always be speedy and secure. Malware is Still Common Malware may not affect geeks, but it certainly continues to affect average people. Securing Windows, keeping it secure, and avoiding unsafe programs is a complex process. There are over 50 different file extensions that can contain harmful code to keep track of. It’s easy to have theoretical discussions about how malware could infect Mac computers, Android devices, and other systems. But Mac malware is extremely rare, and has  generally been caused by problem with the terrible Java plug-in. Macs are configured to only run executables from identified developers by default, whereas Windows will run everything. Android malware is talked about a lot, but Android malware is rare in the real world and is generally confined to users who disable security protections and install pirated apps. Google has also taken action, rolling out built-in antivirus-like app checking to all Android devices, even old ones running Android 2.3, via Play Services. Whatever the reason, Windows malware is still common while malware for other systems isn’t. We all know it — anyone who does tech support for average users has dealt with infected Windows computers. Even users who can avoid malware are stuck dealing with complex and nagging antivirus programs, especially since it’s now so difficult to trust Microsoft’s antivirus products. Manufacturer-Installed Bloatware is Terrible Sit down with a new Mac, Chromebook, iPad, Android tablet, Linux laptop, or even a Surface running Windows RT and you can enjoy using your new device. The system is a clean slate for you to start exploring and installing your new software. Sit down with a new Windows PC and the system is a mess. Rather than be delighted, you’re stuck reinstalling Windows and then installing the necessary drivers or you’re forced to start uninstalling useless bloatware programs one-by-one, trying to figure out which ones are actually useful. After uninstalling the useless programs, you may end up with a system tray full of icons for ten different hardware utilities anyway. The first experience of using a new Windows PC is frustration, not delight. Yes, bloatware is still a problem on Windows 8 PCs. Manufacturers can customize the Refresh image, preventing bloatware rom easily being removed. Finding a Desktop Program is Dangerous Want to install a Windows desktop program? Well, you’ll have to head to your web browser and start searching. It’s up to you, the user, to know which programs are safe and which are dangerous. Even if you find a website for a reputable program, the advertisements on that page will often try to trick you into downloading fake installers full of adware. While it’s great to have the ability to leave the app store and get software that the platform’s owner hasn’t approved — as on Android — this is no excuse for not providing a good, secure software installation experience for typical users installing typical programs. Even Reputable Desktop Programs Try to Install Junk Even if you do find an entirely reputable program, you’ll have to keep your eyes open while installing it. It will likely try to install adware, add browse toolbars, change your default search engine, or change your web browser’s home page. Even Microsoft’s own programs do this — when you install Skype for Windows desktop, it will attempt to modify your browser settings t ouse Bing, even if you’re specially chosen another search engine and home page. With Microsoft setting such an example, it’s no surprise so many other software developers have followed suit. Geeks know how to avoid this stuff, but there’s a reason program installers continue to do this. It works and tricks many users, who end up with junk installed and settings changed. The Update Process is Confusing On iOS, Android, and Windows RT, software updates come from a single place — the app store. On Linux, software updates come from the package manager. On Mac OS X, typical users’ software updates likely come from the Mac App Store. On the Windows desktop, software updates come from… well, every program has to create its own update mechanism. Users have to keep track of all these updaters and make sure their software is up-to-date. Most programs now have their act together and automatically update by default, but users who have old versions of Flash and Adobe Reader installed are vulnerable until they realize their software isn’t automatically updating. Even if every program updates properly, the sheer mess of updaters is clunky, slow, and confusing in comparison to a centralized update process. Browser Plugins Open Security Holes It’s no surprise that other modern platforms like iOS, Android, Chrome OS, Windows RT, and Windows Phone don’t allow traditional browser plugins, or only allow Flash and build it into the system. Browser plugins provide a wealth of different ways for malicious web pages to exploit the browser and open the system to attack. Browser plugins are one of the most popular attack vectors because of how many users have out-of-date plugins and how many plugins, especially Java, seem to be designed without taking security seriously. Oracle’s Java plugin even tries to install the terrible Ask toolbar when installing security updates. That’s right — the security update process is also used to cram additional adware into users’ machines so unscrupulous companies like Oracle can make a quick buck. It’s no wonder that most Windows PCs have an out-of-date, vulnerable version of Java installed. Battery Life is Terrible Windows PCs have bad battery life compared to Macs, IOS devices, and Android tablets, all of which Windows now competes with. Even Microsoft’s own Surface Pro 2 has bad battery life. Apple’s 11-inch MacBook Air, which has very similar hardware to the Surface Pro 2, offers double its battery life when web browsing. Microsoft has been fond of blaming third-party hardware manufacturers for their poorly optimized drivers in the past, but there’s no longer any room to hide. The problem is clearly Windows. Why is this? No one really knows for sure. Perhaps Microsoft has kept on piling Windows component on top of Windows component and many older Windows components were never properly optimized. Windows Users Become Stuck on Old Windows Versions Apple’s new OS X 10.9 Mavericks upgrade is completely free to all Mac users and supports Macs going back to 2007. Apple has also announced their intention that all new releases of Mac OS X will be free. In 2007, Microsoft had just shipped Windows Vista. Macs from the Windows Vista era are being upgraded to the latest version of the Mac operating system for free, while Windows PCs from the same era are probably still using Windows Vista. There’s no easy upgrade path for these people. They’re stuck using Windows Vista and maybe even the outdated Internet Explorer 9 if they haven’t installed a third-party web browser. Microsoft’s upgrade path is for these people to pay $120 for a full copy of Windows 8.1 and go through a complicated process that’s actaully a clean install. Even users of Windows 8 devices will probably have to pay money to upgrade to Windows 9, while updates for other operating systems are completely free. If you’re a PC geek, a PC gamer, or someone who just requires specialized software that only runs on Windows, you probably use the Windows desktop and don’t want to switch. That’s fine, but it doesn’t mean the Windows desktop is actually a good experience. Much of the burden falls on average users, who have to struggle with malware, bloatware, adware bundled in installers, complex software installation processes, and out-of-date software. In return, all they get is the ability to use a web browser and some basic Office apps that they could use on almost any other platform without all the hassle. Microsoft would agree with this, touting Windows RT and their new “Windows 8-style” app platform as the solution. Why else would Microsoft, a “devices and services” company, position the Surface — a device without traditional Windows desktop programs — as their mass-market device recommended for average people? This isn’t necessarily an endorsement of Windows RT. If you’re tech support for your family members and it comes time for them to upgrade, you may want to get them off the Windows desktop and tell them to get a Mac or something else that’s simple. Better yet, if they get a Mac, you can tell them to visit the Apple Store for help instead of calling you. That’s another thing Windows PCs don’t offer — good manufacturer support.

  • Step Away From That Computer! You’re Not Qualified to Use It!

    - by Michael Sorens
    Most things tend to come with warnings and careful instructions these days, but sadly not one of the most ubiquitous appliances of all, your computer. If a chainsaw is missing its instructions, you’re well advised not to use it, even though you probably know roughly how it’s supposed to work. I confess, there are days when I feel the same way about computers. Long ago, during the renaissance of the computer age, it was possible to know everything about computers. But today, it is challenging to be fully knowledgeable even in one small area, and most people aren’t as savvy as they like to think. And, if I may borrow from Edwin Abbott Abbott’s classic Flatland, that includes me. And you. Need an example of what I mean? Take a look at almost any recent month’s batch of Windows updates. Just two quick questions for you: Do you need all of those updates? Is it safe to install all of those updates? I do software design and development for a living on Windows and the .NET platform, but I will be quite candid: I often have little clue what the heck some of those updates are going to do or why they are needed. So, if you do not know why they are needed or what they do, how do you know if they are safe? Of course, one can sidestep both questions by accepting Microsoft’s recommended Windows Update setting of “install updates automatically”. That leads you to infer that you need all of them (which is not always the case) and, more significantly, that they are safe. Quite safe. Ah, lest reality intrude upon such a pretty picture! Sadly, there is no such thing as risk-free software installation, and payloads from Windows Update are no exception. Earlier this year, a Windows Secrets Patch Watch article touted this headline: Keep this troublesome kernel update on hold. It discusses KB 2862330, a security update originally published more than 4 months earlier, and yet the article still recommends not installing it! Most people simply do not have the time, resources, or interest, to go about figuring out which updates to install or postpone or skip for safety reasons. Windows Secrets Patch Watch is the best service I have encountered for getting advice, but it is still no panacea and using the service effectively requires a degree of computer literacy that I still think is beyond a good number of people. Which brings us full circle: Step Away From That Computer! You’re Not Qualified to Use It!

  • Going Paperless

    - by Jesse
    One year ago I came to work for a company where the entire development team is 100% “remote”; we’re spread over 3 time zones and each of us works from home. This seems to be an increasingly popular way for people to work and there are many articles and blog posts out there enumerating the advantages and disadvantages of working this way. I had read a lot about telecommuting before accepting this job and felt as if I had a pretty decent idea of what I was getting into, but I’ve encountered a few things over the past year that I did not expect. Among the most surprising by-products of working from home for me has been a dramatic reduction in the amount of paper that I use on a weekly basis. Hoarding In The Workplace Prior to my current telecommute job I worked in what most would consider pretty traditional office environments. I sat in cubicles furnished with an enormous plastic(ish) modular desks, had a mediocre (at best) PC workstation, and had ready access to a seemingly endless supply of legal pads, pens, staplers and paper clips. The ready access to paper, countless conference room meetings, and abundance of available surface area on my desk and in drawers created a perfect storm for wasting paper. I brought a pad of paper with me to every meeting I ever attended, scrawled some brief notes, and then tore that sheet off to keep next to my keyboard to follow up on any needed action items. Once my immediate need for the notes was fulfilled, that sheet would get shuffled off into a corner of my desk or filed away in a drawer “just in case”. I would guess that for all of the notes that I ever filed away, I might have actually had to dig up and refer to 2% of them (and that’s probably being very generous). That said, on those rare occasions that I did have to dig something up from old notes, it was usually pretty important and I ended up being very glad that I saved them. It was only when I would leave a job or move desks that I would finally gather all those notes together and take them to shredding bin to be disposed of. When I left my last job the amount of paper I had accumulated over my three years there was absurd, and I knew coworkers who had substance-abuse caliber paper wasting addictions that made my bad habit look like nail-biting in comparison. A Product Of My Environment I always hated using all of this paper, but simply couldn’t bring myself to stop. It would look bad if I showed up to an important conference room meeting without a pad of paper. What if someone said something profound! Plus, everyone else always brought paper with them. If you saw someone walking down the hallway with a pad of paper in hand you knew they must be on their way to a conference room meeting. Some people even had fancy looking portfolio notebook sheaths that gave their legal pads all the prestige of a briefcase. No one ever worried about running out of fresh paper because there was an endless supply, and there certainly was no shortage of places to store and file used paper. In short, the traditional office was setup for using tons and tons of paper; it’s baked into the culture there. For that reason, it didn’t take long for me to kick the paper habit once I started working from home. In my home office, desk and drawer space are at a premium. I don’t have the budget (or the tolerance) for huge modular office furniture in my spare bedroom. I also no longer have access to a bottomless pit of office supplies stock piled in cabinets and closets. If I want to use some paper, I have to go out and buy it. Finally (and most importantly), all of the meetings that I have to attend these days are “virtual”. We use instant messaging, VOIP, video conferencing, and e-mail to communicate with each other. All I need to take notes during a meeting is my computer, which I happen to be sitting right in front of all day. I don’t have any hard numbers for this, but my gut feeling is that I actually take a lot more notes now than I ever did when I worked in an office. The big difference is I don’t have to use any paper to do so. This makes it far easier to keep important information safe and organized. The Right Tool For The Job When I first started working from home I tried to find a single application that would fill the gap left by the pen and paper that I always had at my desk when I worked in an office. Well, there are no silver bullets and I’ve evolved my approach over time to try and find the best tool for the job at hand. Here’s a quick summary of how I take notes and keep everything organized. Notepad++ – This is the first application I turn to when I feel like there’s some bit of information that I need to write down and save. I use Launchy, so opening Notepad++ and creating a new file only takes a few keystrokes. If I find that the information I’m trying to get down requires a more sophisticated application I escalate as needed. The Desktop – By default, I save every file or other bit of information to the desktop. Anyone who has ever had to fix their parents computer before knows that this is a dangerous game (any file my mother has ever worked on is saved directly to the desktop and rarely moves anywhere else). I agree that storing things on the desktop isn’t a great long term approach to keeping organized, which is why I treat my desktop a bit like my e-mail inbox. I strive to keep both empty (or as close to empty as I possibly can). If something is on my desktop, it means that it’s something relevant to a task or project that I’m currently working on. About once a week I take things that I’m not longer working on and put them into my ‘Notes’ folder. The ‘Notes’ Folder – As I work on a task, I tend to accumulate multiple files associated with that task. For example, I might have a bit of SQL that I’m working on to gather data for a new report, a quick C# method that I came up with but am not yet ready to commit to source control, a bulleted list of to-do items in a .txt file, etc. If the desktop starts to get too cluttered, I create a new sub-folder in my ‘Notes’ folder. Each sub-folder’s name is the current date followed by a brief description of the task or project. Then all files related to that task or project go into that sub folder. By using the date as the first part of the folder name, these folders are automatically sorted in reverse chronological order. This means that things I worked on recently will generally be near the top of the list. Using the built-in Windows search functionality I now have a pretty quick and easy way to try and find something that I worked on a week ago or six months ago. Dropbox – Dropbox is a free service that lets you store up to 2GB of files “in the cloud” and have those files synced to all of the different computers that you use. My ‘Notes’ folder lives in Dropbox, meaning that it’s contents are constantly backed up and are always available to me regardless of which computer I’m using. They also have a pretty decent iPhone application that lets you browse and view all of the files that you have stored there. The free 2GB edition is probably enough for just storing notes, but I also pay $99/year for the 50GB storage upgrade and keep all of my music, e-books, pictures, and documents in Dropbox. It’s a fantastic service and I highly recommend it. Evernote – I use Evernote mostly to organize information that I access on a fairly regular basis. For example, my Evernote account has a running grocery shopping list, recipes that my wife and I use a lot, and contact information for people I contact infrequently enough that I don’t want to keep them in my phone. I know some people that keep nearly everything in Evernote, but there’s something about it that I find a bit clunky, so I tend to use it sparingly. Google Tasks – One of my biggest paper wasting habits was keeping a running task-list next to my computer at work. Every morning I would sit down, look at my task list, cross off what was done and add new tasks that I thought of during my morning commute. This usually resulted in having to re-copy the task list onto a fresh sheet of paper when I was done. I still keep a running task list at my desk, but I’ve started using Google Tasks instead. This is a dead-simple web-based application for quickly adding, deleting, and organizing tasks in a simple checklist style. You can quickly move tasks up and down on the list (which I use for prioritizing), and even create sub-tasks for breaking down larger tasks into smaller pieces. Balsamiq Mockups – This is a simple and lightweight tool for creating drawings of user interfaces. It’s great for sketching out a new feature, brainstorm the layout of a interface, or even draw up a quick sequence diagram. I’m terrible at drawing, so Balsamiq Mockups not only lets me create sketches that other people can actually understand, but it’s also handy because you can upload a sketch to a common location for other team members to access. I can honestly say that using these tools (and having limited resources at home) have lead me to cut my paper usage down to virtually none. If I ever were to return to a traditional office workplace (hopefully never!) I’d try to employ as many of these applications and techniques as I could to keep paper usage low. I feel far less cluttered and far better organized now.

  • Is SOA really dead?

    - by Ahsan Alam
    I have come across many articles/blogs where authors have strongly hailed the death of Service Oriented Architecture (SOA). I could almost hear the laughter pouring out of their writings. Being a big supporter of SOA, I have found myself wondering – have I been following the wrong path all along? Do I need to change the way I think? Then I started to look around. Many newer technologies and concepts have evolved in the past few years. People are starting to take advantage of cloud computing, SAAS (Software as a Service), multitudes of on-demand platforms and many more. Now, I started thinking – is SOA really dead? In order to effectively utilize these newer concepts, I believe we need SOA more than ever because it gives us loose-coupling. People often forget that the key principal behind SOA is loose-coupling. We cannot achieve SOA just by throwing services (WCF, Web Service); we need loosely coupled systems.

  • How do you structure computer science University notes?

    - by Sai Perchard
    I am completing a year of postgraduate study in CS next semester. I am finishing a law degree this year, and I will use this to briefly explain what I mean when I refer to the 'structure' of University notes. My preferred structure for authoring law notes: Word Two columns 0.5cm margins (top, right, bottom, middle, left) Body text (10pt, regular), 3 levels of headings (14/12/10pt, bold), 3 levels of bulleted lists Color A background for cases Color B background for legislation I find that it's crucial to have a good structure from the outset. My key advice to a law student would be to ensure styles allows cases and legislation to be easily identified from supporting text, and not to include too much detail regarding the facts of cases. More than 3 levels of headings is too deep. More than 3 levels of a bulleted list is too deep. In terms of CS, I am interested in similar advice; for example, any strategies that have been successfully employed regarding structure, and general advice regarding note taking. Has latex proved better than Word? Code would presumably need to be stylistically differentiated, and use a monospaced font - perhaps code could be written in TextMate so that it could be copied to retain syntax highlighting? (Are notes even that useful in a CS degree? I am tempted to simply use a textbook. They are crucial in law.) I understand that different people may employ varying techniques and that people will have personal preferences, however I am interested in what these different techniques are. Update Thank you for the responses so far. To clarify, I am not suggesting that the approach should be comparable to that I employ for law. I could have been clearer. The consensus so far seems to be - just learn it. Structure of notes/notes themselves are not generally relevant. This is what I was alluding to when I said I was just tempted to use a textbook. Re the comment that said textbooks are generally useless - I strongly disagree. Sure, perhaps the recommended textbook is useless. But if I'm going to learn a programming language, I will (1) identify what I believe to be the best textbook, and (2) read it. I was unsure if the combination of theory with code meant that lecture notes may be a more efficient way to study for an exam. I imagine that would depend on the subject. A subject specifically on a programming language, reading a textbook and coding would be my preferred approach. But I was unsure if, given a subject containing substantive theory that may not be covered in a single textbook, people may have preferences regarding note taking and structure.

  • Does professionalism in job postings matter?

    - by Wings87
    I came across this job posting: http://www.justin.tv/jobs/jobs. The page contains some bad language ("No bulls--t"). I personally find this vaguely offensive, and it would certainly put me off applying to work there: It made me wonder what kind/personality of people work at this company. At least where I'm from (EU), the language would be considered bad form, and it would be seen as badly representing the company. Some job postings seem to go to the other extreme, filled with vacuous people skill descriptions and irrelevant details. It's tempting to dream up pictures of each company based on their job posting. So, does professionalism in job postings matter? Are you inclined to see through bad language, irrelevant corporate speak and so on, or do these affect interest in a job?

  • When will UDS sponsorship final list be announced?

    - by Manish Sinha
    UDS-O is being held at Budapest, Hungary and the sponsorships are open which closes on 28th of March. My question is when will the final list be announced? Will there be more than one month period for people to apply for Visa? e.g. I live in India and when we apply for Schengen Visa for the first time, it takes around 2 weeks for the visa interview(period depends on the rush). Then another week for interview and Visa to be stamped. AFAIK the application, interview and collection has to be done in person. This is all what I have heard. So will Canonical give one month time minimum for people in Eastern part of the world or countries where Schengen countries have tougher rules for visa? It would be great if they could finalize the names a bit faster and announce the list by first week of April. I am hoping Jorge or Jono might come and answer this.

  • Can i make money with my Android Engine or should I focus on game-making?

    - by Roger Travis
    I have dedicated past few month to developing my own android 2d engine. You can see its description, demo and tutorials here http://www.aboxengine.com/ ( jar files will be up in a day or two ). While working on the engine I believed it to be better then most available alternatives ( such as andengine, etc. ) and that people would love to use it in their games and, hopefully, would give me some royalties. Yet as I started posting about my engine on other forums, it start looking like people are only interested in free/opensource engines. Based on your experience, what do you think, is there some way for me to make money with that engine or should I forget about selling it and more focus on making games with it myself? Thanks!

  • How do you differentiate between "box," "machine," "computer" and whatever else?

    - by Corey
    There seems to be a few terms for referring to a computer, especially in the tech world. Different terms seem to be used based on technical expertise. When talking with people with some technical knowledge, I'll refer to it as a machine. When talking to non-technical people (family, friends) I'll call it a computer. On the rare occasion I'm talking about servers, I might call it a box, but even then I'll probably still call it a machine. Is that just me, or do there exist rules already for what to call a computer?

  • How can architects work with self-organizing Scrum teams?

    - by Martin Wickman
    An organization with a number of agile Scrum teams also has a small group of people appointed as "enterprise architects". The EA group acts as control and gatekeeper for quality and adherence to decisions. This leads to overlaps between the team decision and EA decisions. For instance, the team might want to use library X or want to use REST instead of SOAP, but the EA does not approve of that. Now, this can lead to frustration when team decisions are overruled. Taken far enough, it can potentially lead to a situation where the EA people "grabs" all power and the team ends up feeling demotivated and not very agile at all. The Scrum guides has this to say about it: Self-organizing: No one (not even the Scrum Master) tells the Development Team how to turn Product Backlog into Increments of potentially releasable functionality. Is that reasonable? Should the EA team be disbanded? Should the teams refuse or simply comply?

  • SQL SERVER – Transaction Log Full – Transaction Log Larger than Data File – Notes from Fields #001

    - by Pinal Dave
    I am very excited to announce a new series on this blog – Notes from Fields. I have been blogging for almost 7 years on this blog and it has been a wonderful experience. Though, I have extensive experience with SQL and Databases, it is always a good idea that we consult experts for their advice and opinion. Following the same thought process, I have started this new series of Notes from Fields. In this series we will have notes from various experts in the database world. My friends at Linchpin People have graciously decided to support me in my new initiation.  Linchpin People are database coaches and wellness experts for a data driven world. In this very first episode of the Notes from Fields series database expert Tim Radney (partner at Linchpin People) explains a very common issue DBA and Developer faces in their career, when database logs fills up your hard-drive or your database log is larger than your data file. Read the experience of Tim in his own words. As a consultant, I encounter a number of common issues with clients.  One of the more common things I encounter is finding a user database in the FULL recovery model that does not make a regular transaction log backups or ever had a transaction log backup. When I find this, usually the transaction log is several times larger than the data file. Finding this issue is very significant to me in that it allows to me to discuss service level agreements with the client. I get to ask questions such as, are nightly full backups sufficient or do they need point in time recovery.  This conversation has now signed with the customer and gets them to thinking about their disaster recovery and high availability solutions. This issue is also very prominent on SQL Server forums and usually has the title of “Help, my transaction log has filled up my disk” or “Help, my transaction log is many times the size of my database”. In cases where the client only needs the previous full nights backup, I am able to change the recovery model to SIMPLE and shrink the transaction log using DBCC SHRINKFILE (2,1) or by specifying the transaction log file name by using DBCC SHRINKFILE (file_name, target_size). When the client needs point in time recovery then in most cases I will still end up switching the client to the SIMPLE recovery model to truncate the transaction log followed by a full backup. I will then schedule a SQL Agent job to make the regular transaction log backups with an interval determined by the client to meet their service level agreements. It should also be noted that typically when I find an overgrown transaction log the virtual log file count is also out of control. I clean up will always take that into account as well.  That is a subject for a future blog post. If your SQL Server is facing any issue we can Fix Your SQL Server.

  • Renault under threat from industrial espionage, intellectual property the target

    - by Simon Thorpe
    Last year we saw news of both General Motors and Ford losing a significant amount of valuable information to competitors overseas. Within weeks of the turn of 2011 we see the European car manufacturer, Renault, also suffering. In a recent news report, French Industry Minister Eric Besson warned the country was facing "economic war" and referenced a serious case of espionage which concerns information pertaining to the development of electric cars. Renault senior vice president Christian Husson told the AFP news agency that the people concerned were in a "particularly strategic position" in the company. An investigation had uncovered a "body of evidence which shows that the actions of these three colleagues were contrary to the ethics of Renault and knowingly and deliberately placed at risk the company's assets", Mr Husson said. A source told Reuters on Wednesday the company is worried its flagship electric vehicle program, in which Renault with its partner Nissan is investing 4 billion euros ($5.3 billion), might be threatened. This casts a shadow over the estimated losses of Ford ($50 million) and General Motors ($40 million). One executive in the corporate intelligence-gathering industry, who spoke on condition of anonymity, said: "It's really difficult to say it's a case of corporate espionage ... It can be carelessness." He cited a hypothetical example of an enthusiastic employee giving away too much information about his job on an online forum. While information has always been passed and leaked, inadvertently or on purpose, the rise of the Internet and social media means corporate spies or careless employees are now more likely to be found out, he added. We are seeing more and more examples of where companies like these need to invest in technologies such as Oracle IRM to ensure such important information can be kept under control. It isn't just the recent release of information into the public domain via the Wikileaks website that is of concern, but also the increasing threats of industrial espionage in cases such as these. Information rights management doesn't totally remove the threat, but abilities to control documents no matter where they exist certainly increases the capabilities significantly. Every single time someone opens a sealed document the IRM system audits the activity. This makes identifying a potential source for a leak much easier when you have an absolute record of every person who's had access to the documents. Oracle IRM can also help with accidental or careless loss. Often people use very sensitive information all the time and forget the importance of handling it correctly. With the ability to protect the information from screen shots and prevent people copy and pasting document information into social networks and other, unsecured documents, Oracle IRM brings a totally new level of information security that would have a significant impact on reducing the risk these organizations face of losing their most valuable information.

  • Why do you use not free software and what not free software do you use?

    - by 0101
    I prefer to use free software, because I believe its more universal(I can use it anywhere, I can tell people about it and they will have no problem with using it) - i like to say "learn once, use anywhere". I was wondering why people use not free software when free alternatives exists?(for example JIRA, Clover for code coverage, not free marge tools, etc.). P.S. I only use TotalCmd that is not free, but I was not able to find any good alternative(I even wrote one myself, but It was not as great). P.S. I dont want to start any flamewar, Im just curious what is your take on it.

  • Is the science of Computer Science dead?

    - by Veaviticus
    Question : Is the science and art of CS dead? By that I mean, the real requirements to think, plan and efficiently solve problems seems to be falling away from CS these days. The field seems to be lowering the entry-barrier so more people can 'program' without having to learn how to truly program. Background : I'm a recent graduate with a BS in Computer Science. I'm working a starting position at a decent sized company in the IT department. I mostly do .NET and other Microsoft technologies at my job, but before this I've done Java stuff through internships and the like. I personally am a C++ programmer for my own for-fun projects. In Depth : Through the work I've been doing, it seems to me that the intense disciplines of a real science don't exist in CS anymore. In the past, programmers had to solve problems efficiently in order for systems to be robust and quick. But now, with the prevailing technologies like .NET, Java and scripting languages, it seems like efficiency and robustness have been traded for ease of development. Most of the colleagues that I work with don't even have degrees in Computer Science. Most graduated with Electrical Engineering degrees, a few with Software Engineering, even some who came from tech schools without a 4 year program. Yet they get by just fine without having the technical background of CS, without having studied theories and algorithms, without having any regard for making an elegant solution (they just go for the easiest, cheapest solution). The company pushes us to use Microsoft technologies, which take all the real thought out of the matter and replace it with libraries and tools that can auto-build your project for you half the time. I'm not trying to hate on the languages, I understand that they serve a purpose and do it well, but when your employees don't know how a hash-table works, and use the wrong sorting methods, or run SQL commands that are horribly inefficient (but get the job done in an acceptable time), it feels like more effort is being put into developing technologies that coddle new 'programmers' rather than actually teaching people how to do things right. I am interested in making efficient and, in my opinion, beautiful programs. If there is a better way to do it, I'd rather go back and refactor it than let it slide. But in the corporate world, they push me to complete tasks quickly rather than elegantly. And that really bugs me. Is this what I'm going to be looking forward to the rest of my life? Are there still positions out there for people who love the science and art of CS rather than just the paycheck? And on the same note, here's a good read if you haven't seen it before The Perils Of Java Schools

  • Live from ODTUG - Big Data and SQL session #2

    - by Jean-Pierre Dijcks
    Sitting in Dominic Delmolino's session at ODTUG (KScope 12). If the session count at conferences is any indication then we will see more and more people start to deploy MapReduce in the database. And yes, that would be with SQL and PL/SQL first and foremost. Both Dominic and our own Bryn Llewellyn are doing MapReduce in the database presentations.  Since I have seen both, I would advice people to first look through Dominic's session to get a good grasp on what mappers do and what reducers do, then dive into Bryn's for a bunch of PL/SQL example. The thing I like about Dominic's is the last slide (a recursive WITH statement) to do this in SQL... Now I am hoping that next year we will see tools vendors show off how they work with Hadoop and MapReduce (at least talking about the concepts!!).

  • Poll Results: Foreign Key Constraints

    - by Darren Gosbell
    A few weeks ago I did the following post asking people – if they used foreign key constraints in their star schemas. The poll is still open if you are interested in adding to it, but here is what the chart looks like as of today. (at the bottom of the poll itself there is a link to the live results, unfortunately I cannot link the live results in here as the blogging platform blocks the required javascript)   Interestingly the results are fairly even. Of the 78 respondents, fractionally over half at least aim to start with referential integrity in their star schemas. I did not want to influence the results by sharing my opinion, but my personal preference is to always aim to have foreign key constraints. But at the same time, I am pragmatic about it, I do have projects where for various reasons some constraints are not defined. And I also have other designs that I have inherited, where it would just be too much work to go back and add foreign key constraints. If you are going to implement foreign keys in your star schema, they really need to be there at the start. In fact this poll was was the result of a feature request for BIDSHelper asking for a feature to check for null/missing foreign keys and I am entirely convinced that BIDS is the wrong place for this sort of functionality. BIDS is a design tool, your data needs to be constantly checked for consistency. It's not that I think that it's impossible to get a design working without foreign key constraints, but I like the idea of failing as soon as possible if there is an error and enforcing foreign key constraints lets me "fail early" if there are constancy issues with my data. By far the biggest concern with foreign keys is performance and I suppose I'm curious as to how often people actually measure and quantify this. I worked on a project a number of years ago that had very large data volumes and we did find that foreign key constraints did have a measurable impact, but what we did was to disable the constraints before loading the data, then enabled and checked them afterwards. This saved as time (although not as much as not having constraints at all), but still let us know early in the process if there were any consistency issues. For the people that do not have consistent data, if you have ETL processes that you control that are building your star schema which you also control, then to be blunt you only have yourself to blame. It is the job of the ETL process to make the data consistent. There are techniques for handling situations like missing data as well as  early and late arriving data. Ralph Kimball's book – The Data Warehouse Toolkit goes through some design patterns for handling data consistency. Having foreign key relationships can also help the relational engine to optimize queries as noted in this recent blog post by Boyan Penev

  • Small projects using the cathedral model: does open-source lower security?

    - by Anto
    We know of Linus' law: With enough eyeballs all bugs are shallow In general, people seem to say that open-source software is more secure because of that very thing, but... There are many small OSS projects with just 1 or 2 developers (the cathedral model, as described by ESR). For these projects, does releasing the source-code actually lower the security? For projects like the Linux kernel there are thousands of developers and security vulnerabilities are quite likely going to be found, but when just some few people look through the source code, while allowing crackers (black hat hackers) to see the source as well, is the security lowered instead of increased? I know that the security advantage closed-source software has over OSS is security through obscurity, which isn't good (at all), but it could help to some degree, at least by giving those few devs some more time (security through obscurity doesn't help with the if but with the when). EDIT: The question isn't whether OSS is more secure than non-OSS software but if the advantages for crackers are greater than the advantages for the developers who want to prevent security vulnerabilities from being exploited.

  • Work at Oracle as a Fresh Student by Ang Sun

    - by Nadiya
    The past months have flown by since I started working at Oracle; but at the same time it feels like I’ve been here forever. I came to Beijing to find a job after I graduated from The University of Southampton with a MSc in Software Engineering. I got an offer the next day after I had an interview with my manager. This new style of working life hasn’t been a problem with me. The atmosphere here is fantastic and everyone is so friendly and easy to talk to. I am the first member in our AIE China Team. We do appreciate those colleagues from Core I/O team who helped us a lot to familiarize ourselves with the new environment. After hire orientation training I got to know many new people from various teams including Middleware, People Soft and Solaris. Also Oracle provides weekly system online training as additional training for those people who need it. The best thing about working at Oracle is that there is a balance between work and rest. It’s good to have a really nice park and green space near the Oracle buildings. Most of us like to walk around the riverside after lunch before we get back to work. I like to grab a cup of latte before discussing issues and the schedule of our projects in a weekly conference call with my US colleagues. It has been great experience; I am working alongside talented colleagues from different countries and nationalities.

  • How to interview my future team leader?

    - by Stormenet
    Our current team leader is quitting his job (starting his own company) and thus we are searching for a new team leader. It's a small team of 4 people (Team leader included). Since it's a small team we expect the team leader not to only manage us but also do some coding. Because of this I convinced the R&D manager to let me have a say in this so that I can evaluate his technical skills and managing skills. I have little experience interviewing people let alone my future Team leader. What I search in a team leader is someone who isn't running a dictatorship but someone that when there are issues there is a discussion about it and we take everyone on the same line. What are the things I should not forget to ask and what are the skills I should find in that person?
