• Is my current employer expecting too much?

  - by priyank patel

  This is my first job as a programmer.I am working on ASP.NET/C#,HTML,CSS,Javascript/Jquery. I am working for a firm which develops software for small banking firms. Currently they have their software running in 100 firms.Their software is developed in Visual Fox Pro. I was hired to develop online version of this software.I am the solo developer. My boss is another developer.So my company has two developers. My boss doesnot have any idea about .NET development.I am working on their project since 8 months.The progress is surely there but not very big. I try my best to do what my boss asks.But the project just seems too ambitious for me. The company doesnot have any planning for the project.They just ask me to develop what their older software provides.So I have to deal with front end , back end,review codes , design architecture and etc. I have decided to give my best.I try a lot.But the project sometimes just seems to be overwhelming. So my questions is , is it normal for a programmer to be in this place. I always feel the need to work in atleast a small team if not big one. Are my employers just expecting too much of a fresher.Or is that I being a programmer am lacking the skills to deal with this. I am just not able judge my condition.Also I am paid very low salary.I do work on saturday as well. Can anyone just help me judge this scenario? Any suggestions are welcome.

• DNS and VPN issues

  - by Lewis

  I recently purchased a year contract for a KVM 512MB VPS running Ubuntu 11.04. I'm having some issues setting up some things on it though - two in particular that I just can't for the life of me figure out. Okay, so I'm trying to setup pptpd as my VPN for my iPhone and my Mac when I'm out on wireless networks. I'm able to login and the chap authenticates but that's as far as I get, no domains will resolve and end up loading forever, I uncommented ms-dns lines as someone had recommended to me and changed the DNS servers to Googles public ones with no luck, is there something I'm missing? (It's probably staring me in the face.) My second issue is that I have managed to setup LAMP but am having a problem with my domain, I have pointed the DNS at 123-reg to my VPS's IP and the 'www .' resolves properly, but when I try to go to the domain without the 'www .' I get the apache landing page ("The web server software is running but no content has been added, yet.") I'm pretty sure there's something I've gotta configure in Apache for the virtual host but I'm missing it. Apart from these minor set-backs I'm enjoying the low-level configuration options of having a VPS and love managing my own server. Thanks!

• Oracle to Join OECD Urban Roundtable for Mayors and Ministers

  - by caroline.yu

  Oracle is pleased to announce that Bastian Fischer, vice president and general manager for EMEA, Oracle Utilities, will participate in the 2010 Organisation for Economic Co-Operation and Development (OECD) Urban Roundtable for Mayors and Ministers on 25 May in France. The roundtable, hosted by OECD Secretary General Angel Gurría, will help determine how cities can contribute to green growth incentives and address the challenges to success. The OECD is developing a global Green Growth Strategy that will identify policies and approaches that can shift production and consumption towards a clean, low-carbon and sustainable economy. Already, more than 500 European cities have signed up to the 2020 carbon pledge to reduce carbon emissions by 20 per cent in ten years. This initiative is driving the adoption of innovative technologies such as the smart gird, which deliver substantial benefits to support this mission by allowing utilities to manage their distribution grids more efficiently, reducing emissions and lowering the risk of outages. A successful smart grid infrastructure will allow green cities to manage their energy usage and succeed in their pledge to meet European targets for carbon reduction, which will undoubtedly be a discussion topic at the roundtable. For more information, visit the OECD Web site.

• Ubuntu 12.04 LTS loops the login screen unless you login as Guest

  - by Mário Silva

  I am running a VMWare Player with a Ubuntu 12.04 LTS Precise Pangloin as Guest on my Windows 7. Sometimes I get the shutdown blue screen error in Windows, this time it happened when I was running the Player. When I restarted everything Ubuntu gave the not so unfamiliar in this forum Login Loop in adminstrator login. I login and there's this black screen where I can only read: "piix4...smbus:0.0.0.07.3 Host Smbus controller not enabled" . When I go to the Prompt in root mode it fails to update and only upgraded, specially some plugins ( I think graphic plugins) which also appear in one an error message after quitting the prompt, but they´are successfully installed. They are not the error message. After that I have been working with the Fail/safe Mode recovery panel. When I try to update via Root I get errors like this: W:failed to fetch http://extras.ubuntu.com/ubuntu/dists/precise/release.gpg could not resolve 'extras/ubuntu.com There are 8 more like this referring to areas like: -archive/canonical.com -ppa.Launchpad.net -security.Ubuntu.com -Us.archive.ubuntu.com - release.gpg precise-updates/release.gpg precise_backport/release.gpg Final Message: some index files failed to download.....they have been ignored or old files are used. The black screens most of the time pass by too fast for me to pick up any information. But in general I think I have done everything I was able to in the recovery panel including updating network and graphic packages and recovering filesystem packages and the basic stuff ( I am a beginner regarding Linux ) in the root prompt. Now I am stuck in this screen with graphic options: - Run in low-graphics mode just for one session - Reconfigure Graphics - Troubleshoot the error - Exit to console login I am trying to choose to reconfigure graphics but the mouse disappears in the virtual machine screen and sometimes when options change ity´s only the first and last option. ut this happens from the blue without messages. This particular option menu is in the regular GUI style against a black screen in Terminal style. Really strange. Thanx in advance, all is welcome and appreciated.

• Problems with both LightDM and GDM using DisplayLink USB monitor

  - by Austin

  When I use LightDM, it will auto-login to desktop just fine. The only problem is Compiz doesn't work, and menus don't work. I can't right-click the desktop, and I can't select program menus in the top bar (I.e clicking "File" does nothing). When I use GDM, I only get a blank blue screen and the mouse cursor. I can't Ctrl+Alt+Backspace to restart, but I can Ctrl+Alt+F1 and Ctrl+Alt+F7 to switch modes. I don't think it's auto-logging me in, but I'm not sure. It plays the login screen noise. Will update with more information when I get home! EDIT: Okay, so I did a fresh install, just to ensure I hadn't borked something playing in the console. I reconfigured my setup as I did before, with the same results. Here's what I followed. The only difference is that instead of setting "vga=normal nomodeset" I set "GRUB_GFXPAYLOAD_LINUX = text". Also I only have the DisplayLink monitor configured in my xorg.conf file. At this point I'm using the open radeon driver, although I used the proprietary ati driver before. I'm not sure if I'm having a problem with: - X configuration - Graphics driver - DisplayLink driver - Unity - LightDM - Compiz - Or something else The resolution of the monitor is 800x480, 16bit. I tried setting a larger virtual resolution of 1200x720 (because the real resolution is lower than the recommended resolution), but it causes Ubuntu to boot into low graphics mode. When I get home I'm going to install the fglrx driver and see if it enables virtual resolutions, which may further enable my window manager to function properly.

• How do I stop someone using my domain for Spam emails?

  - by Vizioz Limited

  Hi Blog Readers,Every now and then I seem to have one of those low life Viagra sellers using my domain for spam emailing people.I have done everything I can think of to try and prevent then from doing this, but they seem to keep doing it. I just wondered if anyone out there new of a way to stop them?The headers from one of the bounce backs look like this:Return-Path: <[email protected]>Received: from rctp.telecomitalia.it (host49-133-dynamic.52-82-r.retail.telecomitalia.it[82.52.133.49]) by mx.google.com with SMTP id o8si307731weq.161.2010.07.23.05.33.53; Fri, 23 Jul 2010 05:33:59 -0700 (PDT)Received-SPF: fail (google.com: domain of [email protected] does not designate 82.52.133.49 as permitted sender) client-ip=82.52.133.49;Authentication-Results: mx.google.com; spf=hardfail (google.com: domain of [email protected] does not designate 82.52.133.49 as permitted sender) [email protected]: <[email protected]>Date: Fri, 23 Jul 2010 14:33:52 +0200From: Garnett Mckinnie <[email protected]>MIME-Version: 1.0To: NAME REMOVE <[email protected]>Subject: Where we are well established we areAs you can see from the headers, I have setup the SPF record and it is receiving a "hardfail"We are using Google Apps for our email hosting, so you'd kinda hope that they have got things pretty much secured down, so what I am missing? Or is it always going to be possible for other people to fake sending emails using another domain?

• Logical progressions through the job market

  - by Philluminati

  I'm 5 years out of a unrecognised university where I did Software Engineering. First job was VB.NET, one job was Python, Linux and Web development. I feel cast as a web developer. I'd love a role doing C but no one is interested in juniors if the applicant hasn't got 3 years of C development experience already. I've done some C and a drop of open source coding but I'll never have the confidence to convince someone I know absolutely what I'm doing. Do I just spend more and more time letting life pass me by as I sit in my room on a friday night writing a C problem "for the sake of learning more C" Basically I'm just not sure I want to continue my career if it's going to involve nothing but high level, machine abstracted, business logic and as interested as I am in low level development and enjoy reading books by Taunembaum I struggle to see how I can make the jump and I just feel life would be easier if I got a job in a cafe in Amsterdam rolling spliffs for customers. My ideal job, being a paid member of the Fedora development team seems so far away, without anyone to pay me to learn the skills to get there, and the only way would be to literally spend weeks and weeks of my life contributing code without recognition for free and without any guarentees at the end. Not that I've contributed anything at all so far. Are there any career paths that are logically set out so that jumping between roles is "correctly" incremental and where hard work and learning does eventually lead to the kind of places I might want to go? [ and also getting paid at the same time? ]

• What are the boundaries between the responsibilities of a web designer and a web developer?

  - by Beofett

  I have been hired to do functional development for several web site redesigns. The company I work for has a relatively low technical level, and the previous development of the web sites were completed by a graphic designer who is self taught as far as web development is concerned. My responsibilities have extended beyond basic development, as I have been also tasked with creating the development environment, and migrating hosting from external CMS hosting to internal servers incorporating scripting languages (I opted for PHP/MySQL). I am working with the graphic designer, and he is responsible for the creative design of the web. We are running into a bit of friction over confusion between the boundaries of our respective tasks. For example, we had some differences of opinion on navigation. I was primarily concerned with ease-of-use (the majority of our userbase are not particularly web-savvy), as well as meeting W3 WAI standards (many of our users are older, and we have a higher than average proportion of users with visual impairment). His sole concern was what looked best for the website, and I felt that the direction he was pushing for caused some functional problems. I feel color choices, images, fonts, etc. are clearly his responsibility, and my expectation was that he would simply provide me with the CSS pages and style classes and IDs to use, but some elements of page layout also seem to fall more under the realm of "usability", which to me translates as near-synonymous with "functionality". I've been tasked with selecting the tools we'll use, which include frameworks, scripting languages, database design, and some open source applications (Moodle for example, and quite probably Drupal in the future). While these tools are quite customizable, working directly with some of the interfaces is beyond his familiarity with CSS, HTML, and PHP. This limits how much direct control he has over the appearance, which has lead to some discussion about the tool choices. Is there a generally accepted dividing line between the roles of a web designer and a web developer? Does his relatively inexperienced background in web technologies influence that dividing line?

• Lexmark X5650 doesn't print (scanning works)

  - by unor

  I want to use a Lexmark X5650 under Ubuntu. When I connect it via USB, Ubuntu recognizes the device, but can't find a driver. On the Lexmark support site, you can select "Unix/Linux" and then "Ubuntu 9.04", "9.10", "10.04" and "10.10". However, all versions lead to the same driver: lexmark-08z-series-driver-1.0-1.i386.deb.sh.tar.gz (Last updated: 2012-04-13). While installing this driver, the installer asks me to connect the device. As soon as I connect it via USB, Ubuntu now adds the printer automatically. So after the installation completed, I had 2 printers set up. But I can't print anything (I tried it with both printer configurations). Scanning works fine, though. So I guess the driver installation and the device connection are successful. When I try to print something, the print job is listed in the printing queue, but nothing happens. After some time, I get an error message which starts a debug wizard, but in the end it reads something like "Sorry, couldn't find the reason". I had several different error messages (unfortunately, I didn't record them), one was approximately like "printer cannot communicate with computer". Another said that my color ink was low (which is true, but black is full). Another said there was an input/output error. I tried it with Ubuntu 11.10. Because I read that some people had success with 10.04., I installed it in QEMU and installed the driver there, too. Same problem, though. I'd like to upgrade to 12.04, if it should work there for any reason, but I read that for some people this printer stopped working in 12.04 :/ So, it would be best if the printer would work in 12.04. If that's not possible, I'd be fine with starting a QEMU virtual machine with any GNU/Linux distribution that works with my printer.

• Rotating object along bezier curve: not rotating enough?

  - by Paul

  I tried to follow the instructions from the threads on the forum (Cocos2d rotating sprite while moving with CCBezierBy) with Unity, in order to rotate my object as it moves along a bezier curve. But it does not rotate enough, the angle is too low, it goes up to 6 instead of 90 for example, as you can see on this image (the y eulerAngle is at 6, I would expect it to be around 90 with this curve) : Would you know why it does this? And how to make the rotation toward the next point? Here is the code (in c# with Unity) : (I am comparing x and z to get the angle, and adding the angle to eulerAngles.y so that it rotates around the y axis) void Update () { if ( Input.GetKey("d") ) start = true; if ( start ){ myTime = Time.time; start = false; } float theTime = (Time.time - myTime) *0.5f; if ( theTime < 1 ) { car.position = Spline.Interp( myArray, theTime );//creates the bezier curve counterBezier += Time.deltaTime; //compare 2 positions after 0.1f if ( counterBezier > 0.1f ){ counterBezier = 0; cbDone = false; newpos = car.position; float angle = Mathf.Atan2(newpos.z - oldpos.z, newpos.x - oldpos.x); angle += car.eulerAngles.y; car.eulerAngles = new Vector3(0,angle,0); } else if ( counterBezier > 0 && !cbDone ){ oldpos = car.position; cbDone = true; } Thanks

• Running Non-profit Web Applications on Cloud/Dedicated Hosting [closed]

  - by cillosis

  Possible Duplicate: How to find web hosting that meets my requirements? I often times build web applications purely because I enjoy it. I like building useful tools or open source applications that don't come with a price tag. That being said, many of these applications can be quite complex requiring services beyond shared hosting (ex. specific PHP extensions). This leaves me with two options: Make the web application less complex and run on shared hosting. Fork out money for cloud or dedicated/VPS hosting. Considering the application is free (I don't make money off of it intentionally), the money for hosting comes out of my own pocket. I know I am not alone in this sticky situation. So the question is, what are the hosting options that provide more advanced features such as shell access via SSH, ability to install specific software/extensions (ex. if I wish to use a NoSQL DB such as Redis, MongoDB, or Cassandra), etc., at a free or low price point? I know free usually equates to bad/unreliable hosting -- but it's not always the case. There are a couple providers with free plans I know of: Amazon EC2 - Free micro-instance for 1 year AppHarbor - Cloud based .NET web application hosting w/ free plan. What else is available for hosting of non-profit applications?

• A better way to encourage contributions to OSS

  - by Daniel Cazzulino

  Currently in the .NET world, most OSS projects are available via a NuGet package. Users have a very easy path towards *using* the project right away. But let’s say they encounter some isssue (maybe a bug, maybe a potential improvement) with the library. At this point, going from user to contributor (of a fix, or a good bug repro or even a spike for a new feature) is a very steep and non trivial multi-step process of registering with some open source hosting site (codeplex, github, bitbucket, etc.), learning how to grab the latest sources, build the project, formulate a patch (or fork the code), learn the source control software they use (mercurial, git, svn, tfs), install whatever tools are needed for it, read about the contributors workflow for the project (do you fork &amp; send pull requests? do you just send a patch file? do you just send a snippet? a unit test? etc.), and on, and on, and on. Granted, you may be lucky and already know the source control system the project uses, but in really, I’d say the chances are pretty low. I believe most developers *using* OSS are far from familiar with them, much less with contributing back to various projects. We OSS devs like to be on the cutting edge all the time, ya’ know, always jumping on the new SCC system, the new hosting site, the new agile way of managing work items, bug tracking, code reviews, etc. etc. etc.. But most of our OSS users are largely the “... Read full article

• New technical product guide for Sun Ray clients

  - by Jaap

  In the Oracle online documentation system a new Sun Ray clients Technical Product guide has been published. The document provides detailed information about the similarities and differences between the three Sun Ray client hardware models: Sun Ray 3, Sun Ray 3 plus and Sun Ray 3i. From the description of the Technical Product guide I want to quote the following section: "......Since Sun Ray 3 Series Clients have no local operating system and require no local management, they eliminate the complexity, expenses, and security vulnerabilities associated with other thin client and PC solutions. ......" This is always one of the great advantages of Sun Ray clients compared to other thin clients (which are actually low-fat PCs where you have to manage thin client OS images). The guide lists the features and technical specifications of the Sun Ray Client such as number of ports, chassis, graphics, network interfaces, power supply, operating conditions, MTBF, reliability, and other standards. The guide also contains a separate chapter about environmental data. As you may know, the Sun Ray 3 Series clients are designed specifically to be sensitive to a spectrum of environmental concerns and standards, from materials to manufacturing processes to shipping, operation, and end of life. The Sun Ray 3 Series clients complies to environmental standards and certifications such as Energy Star 5.0, EPEAT, WEEE and RoHS (see the Oracle policy for RoHS and REACH).

• Input handling between game loops

  - by user48023

  This may be obvious and trivial for you but as I am a newbie in programming I come with a specific question. I have three loops in my game engine which are input-loop, update-loop and render-loop. Update-loop is set to 10 ticks per second with a fixed timestep, render-loop is capped at around 60 fps and the input-loop runs as fast as possible. I am using one of the Javascript frameworks which provide such things but it doesn't really matter. Let's say I am rendering a tile map and the view of which elements are rendered depends on camera-like movement variables which are modified during key pressing. This is only about camera/viewport and rendering, no game physics involved here. And now, how can I handle input events among these loops to keep consistent engine reaction? Am I supposed to read the current variable modified with input and do some needed calculations in a update-loop and share the result so it could be interpolated in a render-loop? Or read the input effect directly inside the render-loop and put needed calculations inside? I thought interpreting user input inside an update-loop with a low tick rate would be inaccurate and kind of unresponsive while rendering with interpolation in the final view. How it is done properly in games overall?

• The Hot-Add Memory Hogs

  - by Andrew Clarke

  One of the more difficult tasks, when virtualizing a server, is to determine the amount of memory that Hypervisor should assign to the virtual machine. This requires accurate monitoring and, because of the consequences of setting the value too low, there is a great temptation to err on the side of over-provisioning. This results in fewer guest VMs and, in fact, with more accurate memory provisioning, many virtual environments could support 30% more VMs. In order to achieve a better consolidation (aka VM density) ratio, Windows Server 2008 R2 SP1 has introduced what Microsoft calls ‘Dynamic Memory’. This means that the start-up RAM VM memory assigned to guest virtual machines can be allowed to vary according to demand, changing dynamically while the VM is running, based on the workload of applications running inside. If demand outstrips supply, then memory can be rationed according to the ‘memory weight’ assigned to the guest VM. By this mechanism, memory becomes a shared resource that can be reallocated automatically as demand patterns vary. Unlike VMWare’s Memory Overcommit technology, the sum of all the memory allocations to each virtual machine will not exceed the total memory of the host computer. This is fine for applications that are self-regulating in their demands for memory, releasing memory back into the 'pool' when not under peak load. Other applications however, such as SQL Server Standard and Enterprise, are by nature, memory hogs under high workload; they can grab hot-add memory whilst running under load and then never release it. This requires more careful setting-up and the SQLOS team have provided some guidelines from for configuring SQL Server in virtual environments. Whereas VMWare’s Memory Overcommit is well-proven in a number of different configurations, Hyper-V’s ‘Dynamic Memory’ is new. So far, the indications are that it will improve the business case for virtualizing and it is probably a far more intuitive technology for the average IT professional to grasp. It is certainly worth testing to see whether it works for you.

• Data structure for pattern matching.

  - by alvonellos

  Let's say you have an input file with many entries like these: date, ticker, open, high, low, close, <and some other values> And you want to execute a pattern matching routine on the entries(rows) in that file, using a candlestick pattern, for example. (See, Doji) And that pattern can appear on any uniform time interval (let t = 1s, 5s, 10s, 1d, 7d, 2w, 2y, and so on...). Say a pattern matching routine can take an arbitrary number of rows to perform an analysis and contain an arbitrary number of subpatterns. In other words, some patterns may require 4 entries to operate on. Say also that the routine (may) later have to find and classify extrema (local and global maxima and minima as well as inflection points) for the ticker over a closed interval, for example, you could say that a cubic function (x^3) has the extrema on the interval [-1, 1]. (See link) What would be the most natural choice in terms of a data structure? What about an interface that conforms a Ticker object containing one row of data to a collection of Ticker so that an arbitrary pattern can be applied to the data. What's the first thing that comes to mind? I chose a doubly-linked circular linked list that has the following methods: push_front() push_back() pop_front() pop_back() [] //overloaded, can be used with negative parameters But that data structure seems very clumsy, since so much pushing and popping is going on, I have to make a deep copy of the data structure before running an analysis on it. So, I don't know if I made my question very clear -- but the main points are: What kind of data structures should be considered when analyzing sequential data points to conform to a pattern that does NOT require random access? What kind of data structures should be considered when classifying extrema of a set of data points?

• Optimizing MySQL -

  - by Josh

  I've been researching how to optimize MySQL a bit, but I still have a few questions. MySQL Primer Results http://pastie.org/private/lzjukl8wacxfjbjhge6vw Based on this, the first problem seems to be that the max_connections limit is too low. I had a similar problem with Apache initially, the max connection limit was set to 100, and the web server would frequently lock up and take an excruciatingly long time to deliver pages. Raising the connection limit to 512 fixed this issue, and I read that raising the connection limit on MySQL to match this was considered good practice. Being that MySQL has actually been "locking up" recently as well (connections have been refused entirely for a few minutes at a time at random intervals) I'm assuming this is the main cause of the issue. However, as far as table cache goes, I'm not sure what I should set this as. I've read that setting this too high can hinder performance further, so should I raise this to right around 551, 560, 600, or do something else? Lastly, as far as raising the join_buffer_size value goes, this doesn't even seem to be included in Debian's my.cnf file by default. Assuming there's not much I can do about adding indexes, should I look into raising this? Any suggested values? Any suggestions in general here would be appreciated as well. Edit: Here's the number of open tables the MySQL server is reporting. I believe this value is related to my question (Opened_tables: 22574)

• How can a non-technical person learn to write a spec for small projects?

  - by Joseph Turian

  How can a non-technical person learn to write specs for small projects? A friend of mine is trying to outsource some development on a statistics project. In particular, he does a lot of work in excel, and wants to outsource the creation of scripts to do what he now does by hand. However, my friend is extremely non-technical. He is poor at writing technical specs. When he does write a spec, it is written the way you would describe doing something in excel (go to this cell and then copy the value to that cell). It is also overly verbose, and does examples several times. I'm not sure if he properly describes corner cases. The first project he outsourced was a failure. I think he overdescribed some details, but underdescribed corner cases. That and/or the coder he hired didn't think through the corner cases and ask appropriate questions. I'm not sure. I got on IM with him and it took me half an hour to dig out a description that should have taken five minutes or less to describe. I wrote the scripts for him at the end, but didn't examine why his process with the coder failed. He has asked me for help. However, I refuse to get involved, because taking his spec and translating it into clear requirements is 10x more work than executing on a clearly written spec. What is the right way for him to learn? Are there resources he could use? Are there ways he can learn from small, low-pressure practice projects with coders? Most of his scripts are statistical and data processing oriented. e.g. take this column and run an average over it. Remove these rows under these conditions. So the challenge is different than spec'ing a web app.

• Learning to be a good developer: what parts can you skip over?

  - by Andrew M

  I have set myself the goal of becoming a decent developer by this time next year. By this I mean full experience of the development 'lifecycle,' a few good apps/sites/webapps under my belt, and most importantly being able to work at a steady pace without getting sidelined for hours by some should-know-this-already technique. I'm not starting from scratch. I've written a lot of html/css, SQL, javascript, python and VB.net, and studied other languages like C and Java. I know about things like OOP, design patterns, TDD, complexity, computational linguistics, pointers/references, functional programming, and other academic/theoretical matters. It's just I can't say I've really done these things yet. So I want to get up to speed, and I want to know what things I can leave till a later date. For instance, studying algorithms and the maths behind them is interesting and all, but so far I've hardly needed to write anything but the most basic nested loops. Investigating Assembly to have a clearer picture of low-level operations would be cool... but I imagine rarely infringes on daily work. On the other hand, looking at a functional programming language might help me write programs that are more comprehensible and less prone to hidden failures (at the moment I'm finding the biggest difficulty is when the complexity of the app exceeds my capacity to understand it - for instance passing data around was fine... until I had to start doing it with AJAX, which was a painful step up). I could spend time working through case studies of design patterns, but I'm not sure how many of them get used in 'real life.' I'm a programmer with basic abilities - what skills should I focus on developing? (also my Unix skills are very weak, and also knowledge of Windows configuration... not sure how much time I should spend on that)
