  • How to proceed when a bug in open source libraries is suspected?

    - by Suma
    We are using some open source libraries in our projects. Sometimes there are some issues found in some of them (most likely library bugs, but it may also be a wrong usage from our side, especially when sometimes documentation is not exactly 100 % complete). As the libraries are often quite complex, debugging them to pinpoint the source of the problem is sometimes quite hard. Can you help me to summarize what other options are there and how to exactly proceed with them? I have just recently hit some strange problems when using TCMalloc (Google scalable memory allocator) on Windows, so I would most welcome answers which would apply to this particular library, but more general answers are good as well. 1) Ask the maintainer/owner of the project for assistance. How can this be done? 2) Hire someone to identify and fix the issue. How to do this? How can I find someone with enough expertise in some particular library? ... any other options?

  • Is it better to specialize in a single field I like, or expand into other fields to broaden my horizons?

    - by Oak
    This is a dilemma about which I have been thinking for quite a while. I'm a graduate student and my topics of interest are programming language design, code analysis, compilation, etc. So far, this field has been very interesting and rewarding for me, so I was thinking about finding a job in that field and continuing to specialize in it. I feel like it's a relatively solid field which won't "get out of style" anytime soon. I've always thought that in such complex fields it's better to be a real expert than just another guy who superficially understand what the experts are talking about. On the other hand, I feel that by specializing this way I really limit my future option. I have always been a strong believer in multidisciplinary approaches to problems. Maybe I should go search for a general programming job in which I could gain experience in other fields, as well as occasionally apply my favorite field for solving problems. Specializing in only one or two fields can prevent me from thinking outside the box and cause stagnation. I would really like to hear more opinions about this choice. The truth is I'm already leaning towards one of the choices, so basic psychology says nothing will change my mind, but I would still love to hear some feedback.

  • How to debug lack of sound in Asus EEE PC

    - by Kalmar
    I have an Asus EEE PC 1225B with fresh Lubuntu 12.04. And no sound. It doesn't seem to be some common problem, so I have to make some research what's up. I tried running alsamixer, so I know I have Realtek ALC269VB with nothing muted unexpectedly. What can I do next to identify and solve the problem? Additional info: alsamixer shows two cards: HD-Audio Generic and HDA ATI-SB (Realtek ALC269VB); the first one is muted. ~$ aplay ALSA lib pcm_dmix.c:1018:(snd_pcm_dmix_open) unable to open slave aplay: main:682: blad otwierania audio: Nie ma takiego pliku ani katalogu The Polish part can be translated as "error opening audio: There is no such file or directory". ~$ sudo lspci -v | grep -A7 -i "audio" 00:01.1 Audio device: Advanced Micro Devices [AMD] nee ATI Wrestler HDMI Audio [Radeon HD 6250/6310] Subsystem: ASUSTeK Computer Inc.

  • TechEd North America 2012–Day 3 #msTechEd #teched

    - by Marco Russo (SQLBI)
    Yesterday I spent the longest day at this TechEd: we talked with many people at Community Night until 9pm and I have to say that just a few months after Analysis Services 2012 has been released, there are many people already using it. And the adoption of PowerPivot is starting to be quite large. Many new ideas and challenging coming from several different real world scenarios. I was tired but really happy. Alberto presented his Many-to-Many Relationships in BISM Tabular session that was in the same time slot of the BI Power Hour. For this reason, very few people attended Alberto’s session so I think many will watch the recorded session (it should be available within a few days). So what about today? I’ll spend some time at Technical Learning Center area (full schedule here) but the most important event today will be the Querying multi-billion rows with many to many relationships in SSAS Tabular (xVelocity) at the Private Cloud, Public Cloud and Data Platform Theater in the Technical Learning Center area (next to the SQL Server 2012 zone).  Why you should attend? Mainly because you will see live demo over 4 billion rows table with many-to-many relationships involved in complex queries. But for those of you that think this is not enough to attend a 15 minute funny session, well, we’ll give away some 8GB USB Memory Keys to those of you that will guess exact response time of queries before execution. Convinced? Join us at 11:15am and don’t be late, the session will finish at 11:30am! After that, we’ll run a book signing session at the Bookstore at 12:30pm and I will be in the Technical Learning Center area at 3:00pm until 5:00pm. See you there!

  • Question aboud Headings For Professionals <H1>... <H9> in SEO & Browsercompatibility Differences

    - by Sam
    We all know the importance ans significance of Headings for Professional Webmasters. These were known for professional developers as <h1>Heading 1</h1> h2 ... h6. As a daring webdeveloper I lately needed more short headings for complex structured document and i thought what the hell and went ahead and used in css h1,h2,h3,h4,h5,h6{ } h7{ } h8{ } h9{ } My experiment turned out to pay back. But only in Firefox, Safari, Chrome etc, not in Internet Explorer 8. Q1. Who(&When) decided that All headings should go upto h6, and not h4 or h7? Q2. Why h7 -h9 work perfect in all major browsers, except IE8? Q3. What is the significance for Bing,Yahoo and Googld in terms of recognition or headings h1 ~ h9? obviously h1 is more important than 2, but do they differentiate between h5 and h6? or not anymore after h3?

  • Oracle is Child&rsquo;s Play&hellip;in NSW

    - by divya.malik
    A few weeks ago, my colleague Michael Seback posted a blog entry on Oracle’s acquisition of Haley.  We recently read  an interesting report from Down Under, and here was our press release on the  implementation of Oracle’s Policy automation software in New South Wales, which I thought I would share. We always love hearing about our software “at work”, and especially in the Public Sector- social services area, where it makes a big difference to people’s lives. Here were some of the reasons, why NSW chose Oracle software: “One of the things Oracle’s Policy Automation system is good at is allowing you take decision  trees and rules that are obviously written in English and code them up using very much a natural language approach,” said Holling (CIO for Human Services). “So it was quite a short process to translate the final set of rules that were written on paper into business rules that were actually embedded in the system.” “Another reason why we chose Oracle’s Automation tool is because with future versions of Siebel it comes very tightly integrated with that. It allows us to then to basically take the results of the Policy Automation survey and actually populate our client management system database with that information,” said Holling. As per Surend Dayal, North America VP, Oracle’s Policy automation has applications across a wide range of industries, including public sector—especially health and human services—also financial services, insurance, and even airline rewards programs. In other words, any business process that requires consistent, accurate decision-making where complex legislation and/or internal policies are involved.

  • You may be tempted by IaaS, but you should PaaS on that or your database cloud journey will be a short one

    - by B R Clouse
    Before we examine Consolidation, the next step in the journey to cloud, let's take a short detour to address a critical choice you will face at the outset of your journey: whether to deploy your databases in virtual machines or not. A common misconception we've encountered is the belief that moving to cloud computing can be accomplished by simply hosting one's current operating environment as-is within virtual machines, and then stacking those VMs together in a consolidated environment.  This solution is often described as "Infrastructure as a Service" (IaaS) because the building block for deployments is a VM, which behaves like a full complement of infrastructure.  This approach is easy to understand and may feel like a good first step, but it won't take your databases very far in the journey to cloud computing.  In fact, if you follow the IaaS fork in the road, your journey will end quickly, without realizing the full benefits of cloud computing.  The better option to is to rationalize the deployment stack so that VMs are needed only for exceptional cases.  By settling on a standard operating system and patch level, you create an infrastructure that potentially all of your databases can share.  Now, the building block will be database instances or possibly schemas within databases.  These components are the platforms on which you will deploy workloads, hence this is known as "Platform as a Service" (PaaS). PaaS opens the door to higher degrees of consolidation than IaaS, because with PaaS you will not need to accommodate the footprint (operating system, hypervisor, processes, ...) that each VM brings with it.  You will also reduce your maintenance overheard if you move forward without the VMs and their O/Ses to patch and monitor.  So while IaaS simply shuffles complex and varied environments into VMs,  PaaS actually reduces complexity by rationalizing to the small possible set of components.  Now we're ready to look at the consolidation options that PaaS provides -- in our next blog posting.

  • I've inherited 200K lines of spaghetti code -- what now?

    - by kmote
    I hope this isn't too general of a question; I could really use some seasoned advice. I am newly employed as the sole "SW Engineer" in a fairly small shop of scientists who have spent the last 10-20 years cobbling together a vast code base. (It was written in a virtually obsolete language: G2 -- think Pascal with graphics). The program itself is a physical model of a complex chemical processing plant; the team that wrote it have incredibly deep domain knowledge but little or no formal training in programming fundamentals. They've recently learned some hard lessons about the consequences of non-existant configuration management. Their maintenance efforts are also greatly hampered by the vast accumulation of undocumented "sludge" in the code itself. I will spare you the "politics" of the situation (there's always politics!), but suffice to say, there is not a consensus of opinion about what is needed for the path ahead. They have asked me to begin presenting to the team some of the principles of modern software development. They want me to introduce some of the industry-standard practices and strategies regarding coding conventions, lifecycle management, high-level design patterns, and source control. Frankly, it's a fairly daunting task and I'm not sure where to begin. Initially, I'm inclined to tutor them in some of the central concepts of The Pragmatic Programmer, or Fowler's Refactoring ("Code Smells", etc). I also hope to introduce a number of Agile methodologies. But ultimately, to be effective, I think I'm going to need to hone in on 5-7 core fundamentals; in other words, what are the most important principles or practices that they can realistically start implementing that will give them the most "bang for the buck". So that's my question: What would you include in your list of the most effective strategies to help straighten out the spaghetti (and prevent it in the future)?

  • Is there a typical career path to learn game development "on the job"?

    - by mac
    The extended version of the question is: what is the typical career paths that a developer without specific experience in game development should take if he/she wishes to work in the game development industry? In other words, what are the positions such a programmer might aspire to get hired for, in the game industry? I am asking because it seems to me that - even without direct experience with 3D modelling, physics engines, shaders, etc... - for as much complex as these topics might be - they are still "just" top layers one can learn "on the job" if he/she has already good programming skills and experience in software design (for example during peer-programming sessions). I have no knowledge whatsoever of the game industry, so maybe I am being naïve here, but for all the other programming jobs I previously took, I learnt most of the specificities while working on concrete projects... so I wonder if there is a chance to do the same with game development. Thanks for your time and advice! :) PS: I don't know if this is important or not for answering the question, but scripting languages are the languages I am more proficient in. /mac

  • 2D Image Creator for a video game

    - by user1276078
    I need to make a few images for an arcade video game I'm making in Java. As of right now, I have drawings that animate, but there are two problems. The drawings are horrible, and as a result, the game won't get enough attention. It's a pain to have to change each coordinate for the drawing, as the drawings are fairly complex. I'd like to use images. I feel they could solve my problem. They would look better than the drawings, and it would only have an x and a y coordinate, rather than the many coordinates I need for each drawing. So, in a sense, I have two questions. Would images actually help? Would they solve my 2 problems? I just want to clarify. How would I make these images. I don't think I can copy them off of the internet because I plan on publishing this game. So, is there any software where you can make your own images? (It has to be in an image type that Java can support. I'm working with java). It also, as stated by the header, needs to be a 2D image; not 3D

  • How to do a 3-tier using PHP [closed]

    - by Ric
    I have a requirement from a client for my PHP Web application to be 3-tier. For example, I would have a web server on Apache in the DMZ, but it should NOT contain any DB connections. It should connect to a Middle server that would host the business objects but be behind the firewall. Then those objects connect to my SQL cluster on another server. I have actually done this using .NET, but I am not sure how to setup my stack using PHP. I suppose I could have my UI front tier call the middle tier using REST based web services if I create my middle tier as a second web server, but this seems overly complex. The main reason for this is advanced security: we can not have any passwords on the DMZ first tier web server. The second reason is scalability - to have multiple server on different tiers that can handle the requests. The Last reason is for deployment - it is easier if I can take one set of servers offline for testing before putting them back in production. Is there a open source project that shows how to do this? The only example I can find is the web server hosting files from a shared drive on another machine (kind of how DotNetNuke pretends to be 3-tier), but that is NOT secure.

  • How does datomic handle "corrections"?

    - by blueberryfields
    tl;dr Rich Hickey describes datomic as a system which implicitly deals with timestamps associated with data storage from my experience, data is often imperfectly stored in systems, and on many occasions needs to retroactively be corrected (ie, often the question of "was a True on Tuesday at 12:00pm?" will have an incorrect answer stored in the database) This seems like a spot where the abstractions behind datomic might break - do they? If they don't, how does the system handle such corrections? Rich Hickey, in several of his talks, justifies the creation of datomic, and explains its benefits. His work, if I understand correctly, is motivated by core the insight that humans, when speaking about data and facts, implicitly associate some of the related context into their work(a date-time). By pushing the work required to manage the implicit date-time component of context into the database, he's created a system which is both much easier to understand, and much easier to program. This turns out to be relevant to most database programmers in practice - his work saves everyone a lot of time managing complex, hard to produce/debug/fix, time queries. However, especially in large databases, data is often damaged/incorrect (maybe it was not input correctly, maybe it eroded over time, etc...). While most database updates are insertions of new facts, and should indeed be treated that way, a non-trivial subset of the work required to manage time-queries has to do with retroactive updates. I have yet to see any documentation which explains how such corrections, or retroactive updates, are handled by datomic; from my experience, they are a non-trivial (and incredibly difficult to deal with) subset of time-related data manipulation that database programmers are faced with. Does datomic gracefully handle such updates? If so, how?

  • Server-side Architecture for Online Game

    - by Draiken
    basically I have a game client that has communicate with a server for almost every action it takes, the game is in Java (using LWJGL) and right now I will start making the server. The base of the game is normally one client communicating with the server alone, but I will require later on for several clients to work together for some functionalities. I've already read how authentication server should be sepparated and I intend on doing it. The problem is I am completely inexperienced in this kind of server-side programming, all I've ever programmed were JSF web applications. I imagine I'll do socket connections for pretty much every game communication since HTML is very slow, but I still don't really know where to start on my server. I would appreciate reading material or guidelines on where to start, what architecture should the game server have and maybe some suggestions on frameworks that could help me getting the client-server communication. I've looked into JNAG but I have no experience with this kind of thing, so I can't really tell if it is a solid and good messaging layer. Any help is appreciated... Thanks ! EDIT: Just a little more information about the game. It is intended to be a very complex game with several functionalities, making some functionalities a "program" inside the program. It is not an usual game, like FPS or RPG but I intend on having a lot of users using these many different "programs" inside the game. If I wasn't clear enough, I'd really appreciate people that have already developed games with java client/server architecture, how they communicated, any frameworks, apis, messaging systems, etc. It is not a question of lack of knowledge of language, more a question for advice, so I don't end up creating something that works, but in the later stages will have to be rewriten for any kind of limiting reason. PS: sorry if my english is not perfect...

  • Microsoft Changes Developer Account Registration Requirements

    - by Tim Murphy
    Over the last couple of weeks I have noticed that Microsoft seems to have changed the requirements for Corporate accounts.  These requirements were not in effect when I originally setup the account for the company that I work for.  We also recently had our corporate account canceled without explanation and are in the process of working to get it reinstated.  This all seems to revolve around rules to increase confidence that in the producers of content.  They are now having Symantec validate a company based on legal documents. In the past there have been problems with getting credit cards accepted.  We have had to setup new Live IDs to satisfy whatever glitch the system had or unexplainable requirement.  I am hoping that in the time that has elapsed these problems have been resolved. In truth I can’t say that these new requirements weren’t always in place, but it is getting frustrating to help clients setup accounts.  I am encourage that they have taken steps to safeguard the consumer from Joe-fly-by-night, but they also need to make sure that the process doesn’t become so complex that it drives away companies from participating in the store.  We will have to keep an eye on this as things evolve. del.icio.us Tags: Windows Phone Development,Windows 8 Development,Windows Phone,Windows 8,Registration,Corporate Accounts

  • What are some efficient ways to set up my environment when working on a remote site?

    - by Prefix
    Hello fellow Programmers, I am still a relatively new programmer and have recently gotten my first on-campus programming position. I am the sole dev responsible for 8 domains as well as 3 small sized PHP web apps. The campus has its web environment divided into staging and live servers -- we develop on the staging via SFTP and then push the updates to the live server through a web GUI. I use Sublime Text 2 and the Sublime SFTP plugin currently for all my dev work (its my preferred editor). If I am just making an edit to a page I'll open that individual file via the ftp browser. If I am working on the PHP web app projects, I have the app directory mapped to a local folder so that when I save locally the file is auto-uploaded through Sublime SFTP. I feel like this workflow is slow and sub-optimal. How can I improve my workflow for working with remote content? I'd love to set up a local environment on my machine as that would eliminate the constant SFTP upload/download, but as I said there are many sites and the space required for a local copy of the entire domain would be quite large and complex; not to mention keeping it updated with whatever the latest on the staging server is would be a nightmare. Anyone know how I can improve my general web dev workflow from what I've described? I'd really like to cut out constantly editing over FTP but I'm not sure where to start other than ripping the entire directory and dumping it into XAMP.

  • Is there a shell-independent HUD-like menu search tool for Gnome?

    - by Redsandro
    The Ubuntu HUD - you love it or you hate it. Personally I rather like a classic desktop, so I use Xfce and Cinnamon, and I don't want to lose my menu in applications. But the HUD is pretty awesome when your menus are complex and you forgot where an option sits. This makes that search trick very interesting. I know the HUD is Unity specific. I am looking for a HUD-like tool to complement the menu in shells other than Unity. There is Appmenu Runner for KDE that does this. There is also appmenu-qt for KDE. Problem with the above is that it uses KDE libs, and it only works for KDE apps. This is Linux, there aught to be something like this for GNOME/GTK apps, right? Looking for any tool that can search the menus. I already use(d) Kupfer and Gnome-do, something like that would suffice if only it includes searching the menus for the currently focussed application.

  • Employers and intellectual property 2

    - by Rick
    I have a question about intellectual property, I am currently a manager in a small manufacturing firm. The owners are driven by greed and don't appreciate the development process of complex machinery and are happy just to send things out half done. I on the other hand think that it should be done properly as breakdown in the field can be costly, embarrassing. They seem to have all of us running around doing most of the work out of hours using the attitude of "Be grateful to have a job" yet no one has a contract or any security or any agreement in place. For a couple of the projects i am using PLC's and doing the code in my own time and the testing during company time, and i am aware that they cannot support their own machines if i left, but as i created the code in my own time who owns it? The have asked my to put in a shutdown code for a maintenance request after a given length of time, could this be classed as criminal damage or anything illegal apart from immoral? (we sell the machines with 12 month warrantee, shut down after) But as time goes on I'm getting rather fed up of the companies attitude toward the client. I am considering keeping the clients as my own and get them to contact me directly In the shutdown code. By doing something like this is a trial version contact me for a full license? I wouldn't feel bad for my current employer as he is not afraid to S***t on people as he has been evolved in numerous law suits and has over 30 failed companies leaving people and customers high and dry, we have took the company this far on the reputation of the workers and and i can see things heading like all the other companies he has owned and taking our reputations with him. So i suppose now i have set the scene, if i code into it to contact me directly in the shutdown could there be any legal impact on me, as i rightly or wrongly think i own the code and designs?

  • The balance between client and server functionality

    - by Eugen Martynov
    I want to bring the discussion that started in our teams and get your opinion about it. Assume we have an user account which could have different credentials for authentication and associated email to recover. An user has possibility to do signup with an email or use his social profile to complete signup process. As an Rest API from the backend to client looks like: Create account Authorise Update user data Link social account Register email Verify email In addition our BE is distributed and divided between several services/servers/clusters. So different calls are related to different end points. In case of the social sign up some of steps should be skipped or simplified. For example, with Facebook signup we could already skip email registration and verification step (we ask email permission form user), linking the social account and pre-fill user displayed name. So we proposed to have another end point which will hide/combine different calls on BE and return whole process result to the clients. The pros for this approach: No more duplication of functionality between clients Speed up the networking and user experience The cons for this approach: Additional work for backend Probably most complex scenarios in future updates I would like to get your opinion or experience with this situation. Especially if you already experienced point #2 from against reasons.

  • ASP.NET MVVM Handling multiple Data Transfer Objects on a single page

    - by meffect
    I have an asp.net mvc "edit" page which allows the user to make edits to the parent entity, and then also "create" child entities on the same page. Note: I'm making these data transfer objects up. public class CustomerViewModel { public int Id { get; set; } public Byte[] Timestamp { get; set; } public string CustomerName { get; set; } public etc.. public CustomerOrderCreateViewModel CustomerOrderCreateViewModel { get; set; } } In my view I have two html form's. One for Customer "edit" Http Posts, and the other for CustomerOrder "create" Http Posts. In the view page, I load the CustomerOrder "create" form in using: <div id="CustomerOrderCreate"> @Html.Partial("Vendor/_CustomerOrderCreatePartial", Model.CustomerOrderCreateViewModel) </div> The CustomerOrder html form action posts to a different controller HttpPost ActionResult than the Customer "edit" Action Result. My concern is this, on the CustomerOrder controller, in the HttpPost ActionResult [HttpPost] public ActionResult Create(CustomerOrderCreateViewModel vm) { if (!ModelState.IsValid) { return [What Do I Return Here] } ...[Persist to database code]... } I don't know what to return if the model state isn't valid. Right now it's not a problem, because jquery unobtrusive validation handles validation on the client. But what if I need more complex validation (ie: the server needs to handle the validation).

  • Beginners guide to developing optimization software

    - by Florenc
    I am novice in "serious" programming i.e. applications that deal with real-life applications and software projects that go beyond school assignments. My interests include optimization, operations research, algorithms and lately i discovered how much I do like software design/development/engineering. I have already developed some simple desktop applications for some "famous" problems like TSP using heuristc approaches, a VRP solver (in progress) and so on. While developing this kind of software I actually used basic concepts taught at school such as object-orientation analysis and design. But, I found these courses rather elementary and quite boring (for my expectations). So I decided to go a little further and start developing "real" software (and this is where I realized how important and interesting software engineering/design is.) Now, here's my issue: I can not find a "study guide" for developing software of this kind. Currently, there are numerous resources out there (books, websites, tutorials) in designing and developing complex IS, web applications, smartphone apps but I can't find a book for example entitled "optimization software development". Definetly, someone could claim that "design patterns apply to software in general" but that's not my point. My point is that I could simply use my imagination for "simple" implementations, but what happens, when my imagination can not go further? In other words I'm looking for a guide/path to bridge the gap between: Mathematics-Algorithm Design-Software Engineering-Optimization-Software development

  • About C# objects and the possibilties it has

    - by user527825
    As a novice programmer and I always wonder about c# capabilities. I know it is still early to judge that but all i want to know is can c# do complex stuffs or something outside windows OS. I think C# is a proprietary language (I don't know if I said that right) meaning you can't do it outside Visual Studio or Windows. Also you can't create your own controller (called object right?) like you are forced to use these available in toolbox and their properties and methods. Can C# be used with OpenGL API or DirectX API Finally it always bothers me when I think I start doing things in Visual Studio, I know it sounds arrogant to say but sometimes I feel that I don't like to be forced to use something even if its helpful, like I feel (do I have the right to feel?) that I want to do all things by myself? Don't laugh I just feel that this will give me a better understanding. Is Visual C# like using MaxScript inside 3ds max in that C# is exclusive to do Windows and Forms and Components that are Windows related and maxscript is only for 3d editing and manipulation for various things in the software. If it is too difficult for a beginner I hope you don't answer the fourth question as I don't have enough motivation and I want to keep the little I have. Note: Sorry for my English, I am self taught and never used the language with native speakers so expect so errors. I have a lot of questions regarding many things, what is the daily ratio you think for asking (number of questions) that would not bother the admins of the site and the members here. Thank you for your time.

  • Can't configure 5.1 audio with 12.04

    I have an Intel ALC892 and a Nvidia GT 520m connected to speakers via HDMI. On lspci, I see 00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02) Subsystem: ZOTAC International (MCO) Ltd.

My sound setting looks like When I use the test dialog, only front left and right have sounds. If I use alsa in XBMC on a 5.1 video, there's no sound. If I use pulseaudio, only front right and left have sound. I can barely hear any speech since I'm guessing it's mapped to front center. Any clues?

  • How can I deal with a difficult developer that is holding back the project? [migrated]

    - by ILovePaperTowels
    Our entire project is being held up because of one piece which is being handled by a single developer. When we did finally got the latest version of his code and started reviewing it, we found the code was horrendous! Its a relatively simply workflow, however the code is so complex that it's very difficult to step through and review/debug. The developer responsible has a hard time accepting any kind of criticism, and feels he is more knowledgeable than others members of the team. It's difficult to even talk to him about his development work because it turns into "I know what I'm talking about and you're just wrong!" type of conversation. A request has already been put in to replace this developer but management is not doing anything. This is probably because devs are in short supply where we are, and this is a corporation has a lot of office drama. I'm just one of the developers, not the project manager, however I really want to see this project succeed. What can I do in this sort of situation to try and keep the project on track?
