• Converting NTFS to ZFS (or other)

  - by NumberFour

  Are there any benefits of converting HDDs that are running NTFS on a Linux machine to ZFS? Is there a way to do such conversion in Linux without losing the data? What about the stability of ZFS on Linux, does FUSE really work well in this case? People say that the only way to get the real full ZFS support is to install Solaris. I understand that the best choice for Linux would be ext4, but I really havent found a way how to convert to ext4 from NTFS without sacrificing all the data. On the other hand I have doubts whether changing from NTFS to ZFS while using Linux is really wise. Thanks for any tips.

• typesetting system

  - by itun

  All my life I used Microsoft Office on Windows for document writing and then Libre(Open)Office on Linux. This is not a bad software, but not perfect and I have some complaints. Now on my usual desktop I have Linux. I heard from people who work a lot with documents of different type and complexity (diagrams, articles, document design, presentation) that latex is a perfect thing. I have spent two days exploring Latex and my opinion as a beginner that it is out-of-date (the concepts of Latex language). The language is not intuitive and sometimes even complex. Can somebody advise another software product for document writing?

• PASS: Total Registrations

  - by Bill Graziano

  At the Summit you’ll see PASS announce the total attendance and the “total registrations”.  The total registrations is the sum of the conference attendees and the pre-conference registrations.  A single person can be counted three times (conference plus two pre-cons) in the total registration count. When I was doing marketing for the Summit this drove me nuts.  I couldn’t figure out why anyone would use total registrations.  However, when I tried to stop reporting this number I got lots of pushback.  Apparently this is how conferences compare themselves to each other.  Vendors, sponsors and Microsoft all wanted to know our total registration number.  I was even asked why we weren’t doing more “things” that people could register for so that our number would be even larger.  This drove me nuts. I understand that many of you are very detail oriented.  I just want to make sure you understand what numbers you’re seeing when we include them in the keynote at the Summit.

• How to deal with a valuable person going in all directions?

  - by JVerstry

  I am working with someone producing user content to be included in a software application. He is not a coder, but rather an expert in his field, sharing the knowledge. His contribution, taken piece by piece is great, but he goes in all directions and has issues producing work sequentially. He works on 25 pieces of content at the same time, and as soon as he reads something 'interesting', he wants to rewrite some of his stuff to improve the quality of it. He does not converge naturally. He collects tons of informations, produces some valuable stuff, but in a completely unstructured way. We addressed this issue with him some time ago and in order to try to solve it, we created a document with the 100 items he had to fill. Problem is, it does not seem to work very well. How to deal with those people and collect information? I was thinking about a new technique: ask him to send his bits, out of order, little by little, as soon as they are ready, and keep a list of what remains to be done, and show him that list to give him direction. This situation is stressing the hell out of me. If his production was not good, I would not be trying so hard to make this work. If you have experience to share, it is welcome.

• How to secure both root domain and wildcard subdomains with one SSL cert?

  - by Question Overflow

  I am trying to generate a self-signed SSL certificate to secure both example.com and *.example.com. Looking at the answers to this and this questions, there seems to be an equal number of people agreeing and disagreeing whether this could be done. However, the website from a certification authority seems to suggest that it could be done. Currently, these are the changes added to my openssl configuration file: [req] req_extensions = v3_req [req_distinguished_name] commonName = example.com [v3_req] subjectAltName = @alt_names [alt_names] DNS.1 = example.com DNS.2 = *.example.com I tried the above configuration and generated a certificate. When navigating to https://example.com, it produces the usual warning that the cert is "self-signed". After acceptance, I navigate to https://abc.example.com and an additional warning is produced, saying that the certificate is only valid for example.com. The certificate details only listed example.com in the certificate hierarchy with no signs of any wildcard subdomain being present. I am not sure whether this is due to a misconfiguration or that the common name should have a wildcard or that this could not be done.

• IIS 7.5 website application pool with 'full control' permissions hackable?

  - by Caroline Beltran

  Although I would never set this permission, I would like to know how a static html website with the permission mentioned in the title could be compromised. In my humble opinion, I would guess that this would pose no threat since a web visitor has no way to upload/edit/delete anything. What if the site was a simple PHP website that simply displayed ‘hello world’? What if this PHP site had a contact us form that was properly sanitized? Thank you EDIT: I should mention that restricting IIS to GET and POST requests only, otherwise people anybody can delete and upload content.

• How to Reap Anticipated ROI in Large-Scale Capital Projects

  - by Sylvie MacKenzie, PMP

  Only a small fraction of companies in asset-intensive industries reliably achieve expected ROI for major capital projects 90 percent of the time, according to a new industry study. In addition, 12 percent of companies see expected ROIs in less than half of their capital projects. The problem: no matter how sophisticated and far-reaching the planning processes are, many organizations struggle to manage risks or reap the expected value from major capital investments. The data is part of the larger survey of companies in oil and gas, mining and metals, chemicals, and utilities industries. The results appear in Prepare for the Unexpected: Investment Planning in Asset-Intensive Industries, a comprehensive new report sponsored by Oracle and developed by the Economist Intelligence Unit. Analysts say the shortcomings in large-scale, long-duration capital-investments projects often stem from immature capital-planning processes. The poor decisions that result can lead to significant financial losses and disappointing project benefits, which are particularly harmful to organizations during economic downturns. The report highlights three other important findings. Teaming the right data and people doesn’t guarantee that ROI goals will be achieved. Despite involving cross-functional teams and looking at all the pertinent data, executives are still failing to identify risks and deliver bottom-line results on capital projects. Effective processes are the missing link. Project-planning processes are weakest when it comes to risk management and predicting costs and ROI. Organizations participating in the study said they fail to achieve expected ROI because they regularly experience unexpected events that derail schedules and inflate budgets. But executives believe that using more-robust risk management and project planning strategies will help avoid delays, improve ROI, and more accurately predict the long-term cost of initiatives. Planning for unexpected events is a key to success. External factors, such as changing market conditions and evolving government policies are difficult to forecast precisely, so organizations need to build flexibility into project plans to make it easier to adapt to the changes. The report outlines a series of steps executives can take to address these shortcomings and improve their capital-planning processes. Read the full report or take the benchmarking survey and find out how your organization compares.

• Storage setup for large files

  - by Mecca

  I need to store over 200TB of data (all types, biggest being video files) and be able to access it over a local network. The files will be accessed for editing or searches. I don't need versioning, but a setup that would keep me safe from harddrive failures would be nice. Right now the content is on different harddrives, some external drives, some regular. I don't exclude the possibility of buying new/extra drives if necessary. If they will ever be exposed to the web, it wont be to the public, but just a couple of people. I have no idea what to buy to make this happen. I see some NAS solutions over the internet like this http://www.bestbuy.com/site/a/2266043.p?id=1218317764591&skuId=2266043 but the storage is not enough, plus it doesn't seem to be scalable. What do you recommend? Thanks

• What should I recommend a small company looking for C# developers

  - by Coder

  Here is the issue. I am a senior developer, and one of the start-ups I designed the system (management system/database/web) a long time ago, have grown and need software updates. I have left their system to another developer long time ago, but apparently he has left the job, and so they are asking me if I can suggest them where to find a new one. The problem is that the company has no clue that the IT is not cheap. They expect multiple features to be added for 40$, so that's an issue. Actually one of the reasons why I left the project when I did. Lots of expectations, little pay, also I know those people outside work, so I decided to avoided stressing the nonwork-relationships and left the project gracefully. Today they asked me for an advice, and I told them that the feature list they want is probably going to cost some if they'll get a senior developer for the job. So I guess their best bet is to find someone who loves coding and has just finished the school. Which would give someone a chance to code for money which is good for a student, and at the same time, allow the student to get some hands on experience. Then again, the system is not exactly 20 line console program, there is an MSSQL database, ASP.NET web page and content management system with all the AJAX stuff and some other things. So student straight out of school could have some problems with that. But, I thought about the issue some more, and I think that junior developer is a tricky deal, without mentoring, he can either screw up royally, or just do what's asked. Also, it seems no one is coming to interviews at all, which is weird, or maybe not. What should I suggest them?

• Advantages of a deployment tool over shell

  - by Jimmy

  Currently I have all of my deployment scripts in shell, which installs about 10 programs and configures them. The way I see it shell is a fantastic tool for this: Modular: Only one program per script, this way I can spread the programs across different servers Simple: Shell scripts are extremely simple and don't need any other software installed One-click: I only have to run the shell script once and everything is setup Agnostic: Most programmers can figure out shell, and don't need to know how to use a specific program. Versioning: Since my code is on github a simple git pull and restart all of supervisor will run my latest code. My question is, with all of these advantages, why is it people are constantly telling me to use a tool such as ansible or chef, and not to use shell.

• How is determined an impact of a requirement change on the existing code?

  - by MainMa

  Hi, How companies working on large projects evaluate an impact of a single modification on an existing code? Since my question is probably not very clear, here's an example: Let's take a sample business application which deals with tasks. In the database, each task has a state, 0 being "Pending", ... 5 - "Finished". A new requirement adds a new state, between 2nd and 3rd one. It means that: A constraint on the values 1 - 5 in the database must be changed, Business layer and code contracts must be changed to add a new state, Data access layer must be changed to take in account that, for example the state StateReady is now 6 instead of 5, etc. The application must implement a new state visually, add new controls for it, new localized strings for tool-tips, etc. When an application is written recently by one developer, it's more or less easy to predict every change to do. On the other hand, when an application was written for years by many people, no single person can anticipate every change immediately, without any investigation. So since this situation (such changes in requirements) is very frequent, I imagine there are already some clever techniques and ways to predict the impact. Is there any? Do you know any books which deal about this subject? Note: my question is not related to How do you deal with changing requirements? question. In fact, I'm not interested in evaluating the cost of a change, but rather the way to predict the parts of an application which will be concerned by the change. What will be those changes and how difficult they are really doesn't matter in my question.

• Getting started on Large Projects

  - by Mercfh

  So I just graduated from my College with a B.S. in Comp. Science (although it was a good school, we're the only accredited CS department in our state.....for w/e that means lol) I feel like im a decent programmer, not amazing....but not terrible. Anyways I got my first job about 2 weeks ago, it's a pretty entry level job: firmware development/tester (I know I know people look down on testers...but I gotta start somewhere). Anyways there isn't a whole lot of coding to be had right now (mostly simple stuff) but here soon I have the option of helping out with development (which is what I want to do) Thing is....I have NEVER worked on a huge project. I mean in school sure we had "group" projects but nothing really big. So I'm not super familiar with HUGE classes and such (main language was C++)....Is this something I'll just get used to with time? Some fellow students were used to that with internships and such...but I never got that chance. My job was mostly a "one man job" kinda thing. Mostly little things. Plus in class we never did huge projects anyways. So how do you guys I guess "plan" out these things? Do you use a whiteboard and plan out classes and such....or what. Also...another worry of mine is that I have to use google......ALOT for examples of code, because sometimes I just don't get how something works. Is this normal? It makes me feel sorta.....stupid I guess. I mean "technically" i've had 4-5 years coding experience......but it really only feels like I had 2 years of REAL experience. If that makes any sense? Thanks

• Computer turns off and on after start ..then goes dead

  - by Shiki

  I built a new PC from the following components: - CPU: Intel Core i7 950 - MB: Gigabyte X58A-UD3R - RAM: 2x2gb i7 Corsair memory - VGA: Zotac AMP2 GTX260 - HDD: 1 GreenSATA HDD (Western Digital 500gb RE2) When I turn it on, it goes for a few seconds, fans at maximum speed, then turns off. The again, it starts by itself.. and goes with fans on max speed, nothing happens. First I suspected my PSU. It's a Chieftec 450AA PSU. After I borrowed a Chieftec 550AA PSU, I tried to start with that. Exact same story. Any idea ? Do I need a bigger PSU? Reason why its not localized. I never seen this turn on, off, on. If you give answer for that, it would already help people like me, with the same problem.

• Local dedicated hosting space (own hardware)

  - by Scott

  Where can I find local dedicated hosting space for my own hardware? I know I can rent dedicated hosting from various companies online, but usually I think that means I'm renting their hardware too. I just need a space with a network connection and a power outlet. That's it. How much would this cost? What would I search for? Is it available easily? Or would it only be the sort of thing huge companies would do? I'm in the greater NYC area. It's for a project I'm working on, but the thing's loud and annoying. I'd be willing to pay a little to get it out of sight and out of mind. I don't even care too much about the quality of the network connection. I'd rather not rent other people's hardware cause it probably would cost a fortune to rent a machine like this (tons of ram).

• Is it common to only pay developers for the time they said a project would take?

  - by BAM

  I work at a small startup (<10 people), and I was recently assigned (along with one other developer) to a relatively small project. The project involved moving an existing iOS app to Android. The client told us they had built the app for iOS in 300 man-hours. Not knowing at the time that this figure was completely false, we naively and optimistically assumed that if they could build the app from scratch in that amount of time, we could easily "port" it in a similar amount of time. Therefore, we drafted up a fixed-price contract based on 350 man-hours, with a 5 week deadline. (We are well aware now of how big of a mistake this was... Never let the client tell you how long it's going to take!) Anyway, by week 4 we had already surpassed our 350 hours, and we estimated that there were at least 2 more weeks left on the project. We were told to continue working, but that the company could not afford to pay out on overdue projects anymore. I thought this just meant "be more careful about estimates in the future". However a few weeks later, the company president informed us that we would not be getting paid for any time past 350 man-hours. We argued over the issue for almost an hour. He claimed, however, that this is standard practice for many organizations, and that I was unreasonable for making a big deal out of it. So is this really a common thing, or am I justified in being upset about it? Thanks in advance for any advice!

• Is individual code ownership important?

  - by Jim Puls

  I'm in the midst of an argument with some coworkers over whether team ownership of the entire codebase is better than individual ownership of components of it. I'm a huge proponent of assigning every member of the team a roughly equal share of the codebase. It lets people take pride in their creation, gives the bug screeners an obvious first place to assign incoming tickets, and helps to alleviate "broken window syndrome". It also concentrates knowledge of specific functionality with one (or two) team members making bug fixes much easier. Most of all, it puts the final say on major decisions with one person who has a lot of input instead of with a committee. I'm not advocating for requiring permission if somebody else wants to change your code; maybe have the code review always be to the owner, sure. Nor am I suggesting building knowledge silos: there should be nothing exclusive about this ownership. But when suggesting this to my coworkers, I got a ton of pushback, certainly much more than I expected. So I ask the community: what are your opinions on working with a team on a large codebase? Is there something I'm missing about vigilantly maintaining collective ownership?

• Dell Power Edge R515 - Replacing a Bad Hard Drive in a RAID

  - by LonnieBest

  I've ordered a new hard drive to replace a bad one in a Dell Power Edge R515. The manual covers obvious topics regarding physical replacing of hard drives, but I've never done this before on a production server where RAID is involved. I've heard people talk about this topic, and I've heard that some servers have RAID controllers that are smart enough to allow you to just put in the new drive (hot swap), and then the server will know automatically how to rebuild that drive to be what the old one was to the system. Where do I find the proper procedure for replacing a failed hard drive on a live production Dell Power Edge R515? Can someone with experience tell me how easy or hard this usually is?

• Any Suggestions on How to Soup Up/ Mod a MacBook Pro 13"?

  - by 5arx

  So I've got a mid-2009 MacBook Pro 13". Integrated GPU so not a games machine but fast enough for doing .Net development in VMs. I love the little thing and wanted to give it a Christmas present so thought I'd mod it up a bit and give it a boost. I'm probably going to go for a 500GB Seagate Momentus XT hybrid drive rather than full-on SSD (I need 500GB space) but was wondering if there are any other mods/tweaks people could suggest? I saw something online about swapping a HDD for the DVD drive and wondered if anyone had tried this or similarly drastic mods to the smallest of the MBPs. Cheers.

• Whats a good way to do Collision with 2D Rectangles? can someone give me a tip?

  using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.Xna.Framework; namespace BreakOut { class Field { public static Field generateField() { List<Block> blocks = new List<Block>(); for (int j = 0; j < BlockType.BLOCK_TYPES.Length; j++) for (int i = 0; i < (Game1.WIDTH / Block.WIDTH); i++) { Block b = new Block(BlockType.BLOCK_TYPES[j], new Vector2(i * Block.WIDTH, (Block.HEIGHT + 2) * j + 5)); blocks.Add(b); } return new Field(blocks); } List<Block> blocks; public Field(List<Block> blocks) { this.blocks = blocks; } public void Update(GameTime gameTime, Ball b) { List<Block> removals = new List<Block>(); foreach (Block o in blocks) { if (o.BoundingBox.Intersects(new Rectangle((int)b.pos.X, (int)b.pos.Y, Ball.WIDTH, Ball.HEIGHT))) //collision with blocks { removals.Add(o); } } foreach(Block o in removals) blocks.Remove(o); //removes the blocks, but i need help hitting one at a time } public void Draw(GameTime gameTime) { foreach (Block b in blocks) b.Draw(gameTime); } } } My problem is that My collision in this sucks. I'm trying to add collision with a ball and hitting against a block and then one of the blocks dissapear. The problem i'm having is: When the ball hits the block, it removes it all in one instance. Please people don't be mean and say mean answers to me, im just in highschool, still a nooby and trying to learn more c#/XNA..

• How to combat negative SEO?

  - by Perturbed

  Someone has decided to create a hate blog on a hosted blogging service (wordpress.com) that bashes my company. The blog contains posts that completely flame myself, my service, and contains complete falsehoods about how I run my business. Without going into details, I'm pretty sure the author of this blog is an owner of a competing service (although it is authored completely anonymously). Frankly, I'm not sure if the content would qualify for defamation or not, but I really don't like the idea of spending money on a lawyer to even attempt to prove this. I also have no interest in retorting or even replying to the blog in any sort of way -- I feel this would justify the ludicrous claims that have been posted. Unfortunately, whoever wrote the blog was pretty smart about using key words that people commonly use to search for my service. Because my customer base is relatively small and local, our PageRank is not incredibly high. As a result, when someone Google's our business name, this blog is usually within the top five results (thankfully, it's never above the business' actual website, but it's usually within eyeshot). It's incredibly frustrating to hear from customers who have seen the link (luckily, most of the time they think the author is crazy). Is there anything I can do to combat this? Would it be worthwhile to setup my own hosted wordpress.com branded blog, in an effort to trump this wordpress.com with a blog that is more active of my own? TL;DR: Someone made a hate blog using wordpress.com and is now on the first page of my business' search results. What are my options?

• Video screen recording + add text (subtitle), export as .flv. What programs?

  - by RasmusWriedtLarsen

  I have to record a video to showcase a tool I've made. It's going to include my talking, but I also want some overlay text (subtitles) for people who doesn't have sound. I'm looking for a program that will let me add a text overlay (as subtitle) for my video, and if possible, export it as .flv . I've tried this so far: Used CamStudio for recording, using their lossless format. Converted the .avi file to a .flv using Any Video Converter (free version) I've been having some trouble with the output of CamStudio, some programs can't play the file right, it skips forward and backward. (VLC, Adobe Media Encoder CS4) So I'm looking for a program that accepts videos from CamStudio*, can add text to my video, and hopefully export as flv. *(If that's not possible I'm open for other recording programs). I'd like to ONLY use free programs, and I'm on Windows XP. Looking forward to your help :)

• What are some good resources for creating a game engine in XNA?

  - by Glasser

  I'm currently a student game programmer working on an indie project. We have a team of eleven people (five programmers, four artists, and two audio designers) aboard, all working hard to help design this game. We've been meeting for months now and so far we have a pretty buffed out Game Design Document as well as much audio/visual concept art. Our programmers are itching to progress on our own end. Each person in our programming team is well versed in C++, but is very familiar with C#. We have enough experience and skill that we're confident that we will be successful with our game, and we're looking to build our own game engine in XNA as it seems like it would be worth our time and effort in the end. The game itself will be a 2D beat 'em up style game to be released over xbox live and the PC. It's play style will be similar to that of Castle Crashers or Scott Pilgrim vs The World. We want to design the game engine to allow us to better implement our assets into the game as well as to simplify the creation of design elements/mechanics. Currently between our programmers, we have books such as "XNA 4.0" and "Game Coding Complete, Third Edition," but we'd still like more information on both XNA and (especially) building a game engine from scratch. What are any other good books, websites, or resources we could use to further map out and program our game engine?

• What are all the components of a "Facebook App"?

  - by pnongrata

  I am a developer who has never personally partaken in social media (in any form) for reasons completely outside the scope of this question. I am "off the grid" (no Facebook, Twitter, etc accounts). I'm currently building a web app and would like the app to have a presence on Facebook, and possibly even "port" my app over as a Facebook app. My understanding of Facebook Apps is that they're just normal web apps that get <iframe>d into a Facebook page. The app is actually hosted on your server (not FB's servers). But this got me thinking: Don't Facebook Apps have "profile pages"? Is there anything developers can do to customize the behavior of their own profile pages? Do apps have the ability to do things like MySpace themes used to do (i.e., customize and interact with User profile pages, Groups, etc.)? Do Facebook Apps gain any sort of extra capabilities (inside of Facebook) that a normal web app would not have? It seems to me like if all a Facebook App is, is an iframed-web app, that it would still need to communicate with Facebook via its many APIs, just like a normal app would have to, right? If it's not possible to write an app that can customize the UI or behavior of user profiles and other pages, then how do games like "Farmville" interact with User profiles so that you see updates to profiles like "John Smith reached level 2 of Farmville"? Basically, I'm asking any battle-worn Facebook app developers if my understanding of Facebook Apps is correct, or if I'm missing anything big here. It's my understanding that for security reasons (obviously) Facebook doesn't allow apps to customize anything outside of the iframe it lives in. So if I want my app to appear like it's "interacting" with its Facebook users, it looks like I just need to publish stuff to the users' news feeds to try and encourage people to use my app (please correct me if I'm wrong here!). Thanks in advance for any corrections, clarifications, advice or suggestions!

• Learning curve webdevelopment

  - by refro

  At the moment our team has a huge challenge, we're being asked to deliver a new GUI for an embedded controller. De deadline is very tight and is set on april 2013. Our team is very diverse some people are on the level of functional programming (mostly C), others (including myself) also master object oriented programming (C++, C#). We build a prototype with android, although it has its quirks it is mostly just OO. For the future there is a wish to support multiple platforms (Windows, Android, iOS). In my opinion a HTML5 app with a native app shell is the way to go. When gathering more information on the frameworks to use etc it becomes obvious to me a paradigm shift is needed. None of us have a web background so we need to learn from the ground up. The shift from functional to oo took us about 6 months to become productive (and some of the early subsystems were rewritten because they were a total mess) . Can we expect the learning curve to be similar? Can this be pulled off with a webapp? (My feeling says it will already be hard to pull off as a native app which is at the edge of our comfort zone)

• How useful is mounting /tmp noexec?

  - by Novelocrat

  Many people (including the Securing Debian Manual) recommend mounting /tmp with the noexec,nodev,nosuid set of options. This is generally presented as one element of a 'defense-in-depth' strategy, by preventing the escalation of an attack that lets someone write a file, or an attack by a user with a legitimate account but no other writable space. Over time, however, I've encountered arguments (most prominently by Debian/Ubuntu Developer Colin Watson) that noexec is a useless measure, for a couple potential reasons: The user can run /lib/ld-linux.so <binary> in an attempt to get the same effect. The user can still run system-provided interpreters on scripts that can't be run directly Given these arguments, the potential need for more configuration (e.g. debconf likes an executable temporary directory), and the potential loss of convenience, is this a worthwhile security measure? What other holes do you know of that enable circumvention?
