  • NSMutableDictionary confused over how to use keys with certain code ?

    - by Jules
    I'm getting data from a database and I need to add the string field value and the record id. However, I need this to work with some existing code... I'm replacing this (see code below) and getting data from my database. NSDictionary *dict = [[NSDictionary alloc] initWithContentsOfFile:path]; self.allCategories = dict; [dict release]; But needs to work with these key and value search functions. - (void)resetSearch { NSMutableDictionary *allCategoriesCopy = [self.allCategories mutableDeepCopy]; self.Categories = allCategoriesCopy; [allCategoriesCopy release]; NSMutableArray *keyArray = [[NSMutableArray alloc] init]; [keyArray addObject:UITableViewIndexSearch]; [keyArray addObjectsFromArray:[[self.allCategories allKeys] sortedArrayUsingSelector:@selector(compare:)]]; self.keys = keyArray; [keyArray release]; } . - (void)handleSearchForTerm:(NSString *)searchTerm { NSMutableArray *sectionsToRemove = [[NSMutableArray alloc] init]; [self resetSearch]; for (NSString *key in self.keys) { NSMutableArray *array = [Categories valueForKey:key]; NSMutableArray *toRemove = [[NSMutableArray alloc] init]; for (NSString *name in array) { if ([name rangeOfString:searchTerm options:NSCaseInsensitiveSearch].location == NSNotFound) [toRemove addObject:name]; } if ([array count] == [toRemove count]) [sectionsToRemove addObject:key]; [array removeObjectsInArray:toRemove]; [toRemove release]; } [self.keys removeObjectsInArray:sectionsToRemove]; [sectionsToRemove release]; [table reloadData]; } Keep getting an error from this code... NSDictionary *arrayTmp= [[NSDictionary alloc] init]; ... loop records int cid = sqlite3_column_int(statementTMP, 0); NSString *category = [[NSString alloc] initWithUTF8String:(char *)sqlite3_column_text(statementTMP, 1)]; [arrayTmp setObject:category forKey:[NSString stringWithFormat:@"%i", cid]]; Error caused by line above * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSCFString count]: unrecognized selector sent to instance 0x4d4c500' * Call stack at first throw * ... end loop self.allCategories = arrayTmp; [arrayTmp release];

  • Looking forward to a programming future but confused where to start.

    - by Kraivyne
    Hi there, I am very new to this site and to programming. I started doing some basic programming with python a few weeks ago and recently, messing around with Java basics. My main problem is that I am completely overwhelmed and haven't got the slightest clue where I should be starting. I want to learn programming because I really enjoy doing it, the simple applications that I have managed to conjure up put a smile on my face. My plan is to eventually (by eventually I'm talking about 6 years+) go into games programming. I have been informed that C++ is the best way to go about this but haven't got the slightest clue what book/sight is optimal for someone who is still learning the very basics. These are my questions: I have been to the Definitive C++ Book Guide but am still unsure which book is best to start of with. Should I stick with Python or Java instead of moving on to C++? Is there any advice you would give to a beginner programmer? Thanks again for all your help.

  • Anyone know about AppDynamics? Does Microsoft already have something similiar? Event viewer? Im confused

    - by punkouter
    We have a big collection of java (80%) and .Net (20%) apps.. And the people in charge want a way to monitor the applications somehow. So they told me they are interested in AppDynamics? I have spent a bit looking into it but I still don't get it. Can someone tell me what its about ? From my understanding it seems like you would someone inject the AppDynamics API in your code to tell about differnt events that occur? So sounds like Event Viewer ? I am on the .NET side of this and seems to me we can just write data to a log and report off of that data.. I don't get what the additional complexity of using'AppDynamics' does. Maybe it is overkill ??

  • Grid pathfinding with a lot of entities

    - by Vee
    I'd like to explain this problem with a screenshot from a released game, DROD: Gunthro's Epic Blunder, by Caravel Games. The game is turn-based and tile-based. I'm trying to create something very similar (a clone of the game), and I've got most of the fundamentals done, but I'm having trouble implementing pathfinding. Look at the screenshot. The guys in yellow are friendly, and want to kill the roaches. Every turn, every guy in yellow pathfinds to the closest roach, and every roach pathfinds to the closest guy in yellow. By closest I mean the target with the shortest path, not a simple distance calculation. All of this without any kind of slowdown when loading the level or when passing turns. And all of the entities change position every turn. Also (not shown in screenshot), there can be doors that open and close and change the level's layout. Impressive. I've tried implementing pathfinding in my clone. First attempt was making every roach find a path to a yellow guy every turn, using a breadth-first search algorithm. Obviously incredibly slow with more than a single roach, and would get exponentially slower with more than a single yellow guy. Second attempt was mas making every yellow guy generate a pathmap (still breadth-first search) every time he moved. Worked perfectly with multiple roaches and a single yellow guy, but adding more yellow guys made the game slow and unplayable. Last attempt was implementing JPS (jump point search). Every entity would individually calculate a path to its target. Fast, but with a limited number of entities. Having less than half the entities in the screenshot would make the game slow. And also, I had to get the "closest" enemy by calculating distance, not shortest path. I've asked on the DROD forums how they did it, and a user replied that it was breadth-first search. The game is open source, and I took a look at the source code, but it's C++ (I'm using C#) and I found it confusing. I don't know how to do it. Every approach I tried isn't good enough. And I believe that DROD generates global pathmaps, somehow, but I can't understand how every entity find the best individual path to other entities that move every turn. What's the trick? This is a reply I just got on the DROD forums: Without having looked at the code I'd wager it's two (or so) pathmaps for the whole room: One to the nearest enemy, and one to the nearest friendly for every tile. There's no need to make a separate pathmap for every entity when the overall goal is "move towards nearest enemy/friendly"... just mark every tile with the number of moves it takes to the nearest target and have the entity chose the move that takes it to the tile with the lowest number. To be honest, I don't understand it that well.

  • Ubuntu and Surface Pro, wifi issues not fixed?

    - by Confused or too stupid
    Just a quick question, from the numerous other threads I found, is the wifi still a no go straight out of installing Ubuntu? I tried this Dual boot Surface Pro with Ubuntu? with 13.04, the wifi is sporadic in working. From that and other threads I gathered that 13.10 would include the fix, so I tossed that onto the Surface as well, with the same results. Is there anything I am missing? Is there any other distro that has better luck with the Marvell chip?

  • Internet Connection Problems

    - by Confused One
    I just installed Ubuntu 11.04 onto a laptop. There is no list of automatic connections when I click on the internet connection symbol. Enable Wireless was unchecked, so I checked it. However, it continues saying "wireless is disabled." Soft is blocked, and when I tried rfkill unblock wifi it told me that the device was not ready. I tried to counter this with what I found on this thread but nothing worked. I have tried manually entering my Wireless information, but this does not help. Is there a solution?

  • How to set up a local webDAV server for use with Goodreader on the ipad? [migrated]

    - by confused-about-webdav
    I need to know how to set up a local webDav server on my PC so that goodreader on ipad can automatically sync with it over the local wifi network? I am really a rookie when it comes to setting up a web server and have tried various guides on the internet. I tried setting up a webdav server using IIS and forwarded the required ports and enabled webdav publishing but goodreader can find it in the local wifi network automatically nor is it able to connect even after manually entering the credendtials. So i'll be really greateful if someone who has successfully setup a webdav server for use with goodreader can point me on how to do it?

  • Quit job for another but current employer doesn't want to lose me. Would it be a bad idea to stay?

    - by Confused
    So I've handed in my notice at my current job as I've been offered a job at another company. However, my current employer doesn't want to lose me and they want to know what I want to stay. I mostly enjoy working there so I'd be open to negiotiation. The new job was an unexpected opportunity that presented itself. Such things I'd be looking for are: Better computers for developers Opportunity to work from home occasionally Improved internet access (e.g. able to download software, no keyword blocking) Chance to work on other technologies than my primary (we do have projects on other technologies) Pay increase (though this isn't my primary motivation) I found out that some of these were already in progress when I handed in my notice :( Is it ever a good idea to remain at a company after you've resigned? What if they meet all my conditions and alter my contract accordingly? Will I burn my bridges at the new company (I've already told them I'd accept their offer)? Update: Thanks for the answers. Quite a mixed bag which was interesting. Anyway, just so you know, I've chosen to stay at my current company. So far, it definately feels like the right decision. Guess I won't know for a few months whether is was though.

  • How to make an object stay relative to another object

    - by Nick
    In the following example there is a guy and a boat. They have both a position, orientation and velocity. The guy is standing on the shore and would like to board. He changes his position so he is now standing on the boat. The boat changes velocity and orientation and heads off. My character however has a velocity of 0,0,0 but I would like him to stay onboard. When I move my character around, I would like to move as if the boat was the ground I was standing on. How do keep my character aligned properly with the boat? It is exactly like in World Of Warcraft, when you board a boat or zeppelin. This is my physics code for the guy and boat: this.velocity.addSelf(acceleration.multiplyScalar(dTime)); this.position.addSelf(this.velocity.clone().multiplyScalar(dTime)); The guy already has a reference to the boat he's standing on, and thus knows the boat's position, velocity, orientation (even matrices or quaternions can be used).

  • Planning milestones and time

    - by Ignas
    I was hired by a marketing company a year ago initially for link building / SEO stuff, but I'm actually a Web developer and took the job just in desperation to have one (I'm still quite young and just finished 2nd year of University). From the 3rd day my boss realised that I'm not into that stuff at all and since he had an idea of a web based app we started to plan it. I estimated that it shouldn't take me longer than two months to do it, but as I was making it we soon realised that we want to add more and more stuff to make it even better. So the development on my own lasted for about 4 months, but then it became an enterprise size app and we hired another programmer to work along me. The guy was awesome at what he did, but because I was assigned to be programmer/project manager I had to set up milestones with deadlines and we missed most of them, because most of the time it was too much work, and my lack of experience kept me setting really optimistic deadlines. We still kept adding features and had changed the architecture of the application twice. My boss is a great guy and he gets that when we add features it expands the time frame in which things should be done so he wasn't angry at me nor the other guy. But I was feeling bad (I still am) that I suck at planning. I gained loads of experience from the programming side, but I still lack the management/planning skills which make me go nuts. So over the last year I have dedicated probably about 8 months of work to this app (obviously my studies affected it) and we're launching as a closed beta this month. So my question is how do I get better at planning/managing a project, how do you estimate the times? What do you take into consideration when setting goals. I'm working alone again because the other guy moved from the city. But I'm sure we'll be hiring to help me maintain it so I need to get better at it. Any hints, points or anything on the topic are appreciated.

  • Excel 2007 Macro Changes?

    - by Guy Thomas
    My excel macros are no longer working as designed. Last week they worked as expected, this week a different result. I even tried a two year old version, it did not work the way it used to. Guy's conclusion an Office / Excel update changed the macro behaviour. Am I alone in this conclusion? If so I'll take a different troubleshooting approach.

  • Microsoft DevDays 2010 Day #1

    It's been an eventful day here at Microsoft DevDays 2010, and the show hasn't even officially started! First item of business is to get to a hotel for rest and get some great food-not necessarily in that order. My flight was as good as one can expect- the guy next to me, Jim Anderson, was affable but not overly chatty, and he's a soundman on European tour with The Sonics. Jim was the house-sound guy for the Crocodile Caf for many years, and it was great to talk to a guy who loves audio like I do....Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Any recommendations for a domain buying negotiating service? [closed]

    - by Saunt Valerian
    The best domain for my niche and related is owned by a guy in San Fransisco, and I want to buy the domain from him but I don't want to deal with him directly (even though he has contacted me in the past). I need to find an intermediary company that can handle the negotiation for me. I don't expect to have to pay much since the guy has been squatting on it for more than 15 years and according to the Internet Wayback Machine it has never actually been used for anything at all - he has never added any value to it. It kind of irritates me that such a good domain has been sitting in this guy's closet gather dust for 15 years. I know that GoDaddy has a domain buying negotiating service (and the domain is registered through them, which may make it easier), but I really, really do not want to do business with GoDaddy if I don't have too. Do any of you know of other firms that deal with this sort of thing?

  • Nerdstock 2012: A photo review of Microsoft TechEd North America 2012

    - by The Un-T Guy
    Not only could I not fathom that I would ever be attending a tech event of the magnitude of TechEd, neither could any of my co-workers.  As the least technical person in the history of Information Technology ever, I felt as though I were walking into the belly of the beast, fearing I’d not be allowed out until I could write SSIS packages, program in Visual Basic, or at least arm wrestle a DBA.  Most of my fears were unrealized.   But I made it.  I was here.  I even got to wear the Mark of the Geek neck package with schedule, eyeglass cleaners, name badge (company name obfuscated so they don’t fire me), and a pen.  The name  badge was seemingly the key element, as every vendor in the place wanted to scan it to capture name, email address, and numbers to show their bosses back home.  It also let me eat the food and drink the coffee so that’s a fair trade.   A recurring theme throughout the presentations and vendor demos was “the Cloud” and BYOD (bring your own device).  The below was a common site throughout the week, as attendees from all over the world brought their own devices and were able to (seemingly) seamlessly connect to the Worldwide Innerwebs.  Apparently proof that Microsoft and the event organizers were practicing what they were preaching.   “Cavernous” is one way to describe the downstairs facility itself.  “Freaking cavernous” might be more accurate.  Work sessions were held in classrooms on the second and third floors but the real action was happening downstairs.  Microsoft bookstore, blogger hub (shoutout to Geekswithblogs.net), The Wall (sans Pink Floyd, sadly), couches, recharging stations…   …a game zone with pool and air hockey tables, pinball machines, foosball…   …vintage video games…           …and a even giant chess board.  Looked like this guy was opening with the Kaspersky parry.   The blend of technology and fantasy even went so far as to bring childhood favorites to life.  Assuming, of course, your childhood was pre-video games (like mine) and you were stuck with electric football and Rock ‘em Sock ‘em robots:   And, lest the “combatants” become unruly or – God forbid – afternoon snacks were late, Orange County’s finest was on the scene to keep the peace.  On a high-tech mode of transport, of course.   She wasn’t the only one to think this was a swell way to transition from one concourse to the next.  Given the level of support provided by the entire Orange County Convention Center staff, I knew they had to have some secret.   Here’s one entrance to the vendor zone/”Technical Learning Center.”  Couldn’t help but think of them as the remora attached to the Whale Shark that is Microsoft…   …or perhaps planets orbiting the sun. Microsoft is just that huge and it seemed like every vendor in the industry looks forward to partnering with the tech behemoth.   Aside from the free stuff from the vendors, probably the most popular place in the house was the dining area.  Amazing spreads every day, multiple times a day.  While no attendance numbers were available at press time, literally thousands of attendees were fed, and fed well, every day.  And lest you think my post from earlier in the week exaggerated about the backpacks…   …or that I’m exaggerating about the lunch crowds.  This represents only about between 25-30% of the lunch crowd – it was all my camera could capture at once.  No one went away hungry.   The only thing missing was a a vat of Red Bull but apparently organizers went old school, with probably 100 urns of the original energy drink – coffee – all around the venue.   Of course, following lunch and afternoon sessions, some preferred the even older school method of re-energizing.  There were rumors that Microsoft was serving graham crackers and milk in this area.  But they were only rumors.   Cannot overstate the wonderful service provided by the Orange County Convention Center staff.  Coffee, soft drinks, juice, and water were available always.  Buffet meals were delicious with a wide range of healthy options available, in addition to hundreds (at least) special meal requests supported every day.  Ever tried to keep up with an estimated 9,000 hungry and thirsty IT-ers?  These folks did.  Kudos to all of the staff and many thanks!   And while I occasionally poke fun at the Whale Shark, if nothing else this experience convinced me of one thing:  Microsoft knows how to put on a professional event.  Hundreds of informative, professionally delivered sessions, covering a wide range of topics set at varying levels of expertise (some that even I was able to follow), social activities, vendor partnerships…they brought everything you could ask for to inform, educate, and inspire an entire IT industry.   So as I depart the belly of the beast, I can both take pride in the fact that I survived the week and marvel at the brilliance surrounding me.  The IT industry – or at least the segment associated with Microsoft – is in good, professional hands.  And what won’t fit in their hands can be toted in the Microsoft provided backpacks.  Win-win.   Until New Orleans…

  • Javascript :(….. Oh!! So its jquery? Now what?? I’m a C# Guy

    - by Shekhar_Pro
    Hi guys I want you to Guide me here. This other day I was working out some AJAX for my ASP.Net website and handling client side code in Java was taking the hell out of me. Then I got my hands on this Book jQuery In Action 2nd Edition and solved my problem with the help of Example code in the book. Now as I checked the contents I got an overview that whatever I had ever thought of doing can be done by this jQuery so easily and quite cleanly. I am actually pretty new to web development (say abt 4months ) and from C# world where we have cool libraries and Simple and Elegant coding style. (yeah including those generic, Ienumerable, lambadas, chained statements.. you got it…) and you know what you’re doing when writing some code. And we have so great IntelliSense to care., and above all we have everything Strongly Typed. But in Javascript everything is so messy.. . (and I don’t know why they are not properly indented.. see page source ) Now tell me what should I do, go straight with jQuery or should I first learn Javascript (like a disciplined boy…I even have a book for that too… got in gift :) …. ) I have seen Is it a good idea to learn JavaScript before learning jQuery? but remember I have already got a project on my hand…

  • Cocos2d - smooth sprite movement in tile map RPG

    - by Lendo92
    I've been working on a 2-D Gameboy style RPG for a while now, and the game logic is mostly all done so I'm starting to try to make things look good. One thing I've noticed is that the walking movement / screen movement is a little bit choppy. Technically, it should work fine, but either it seems to be having some quirks, either due to taking up a lot of processing power or just timing inconsistencies between moving the screen and moving the sprite. To move the sprite, once I know where I want to move it, I call: tempPos.y += 3*theHKMap.tileSize.width/5; id actionMove = [CCMoveTo actionWithDuration:0.1 position:tempPos]; id actionMoveDone = [CCCallFuncN actionWithTarget:self selector:@selector(orientOneMove)]; [guy runAction:[CCSequence actions:actionMove, actionMoveDone, nil]]; [self setCenterOfScreen:position]; Then, in orientOneMove, I call: [self.guy setTexture:[[CCTextureCache sharedTextureCache] addImage:@"guysprite07.png"]]; //the walking picture-I change texture back at the end of the movement id actionMove = [CCMoveTo actionWithDuration:0.15 position:self.tempLocation2]; id actionMoveDone = [CCCallFuncN actionWithTarget:self selector:@selector(toggleTouchEnabled)]; [guy runAction:[CCSequence actions:actionMove, actionMoveDone, nil]]; The code for the concurrently running setCenterOfScreen:position method is: id actionMove = [CCMoveTo actionWithDuration:0.25 position:difference]; [self runAction: [CCSequence actions:actionMove, nil, nil]]; So the setCenterOfScreen moves the camera in one clean move while the guy moving is chopped into two actions to animate it (which I believe might be inefficient.) It's hard to tell what is making the movement not perfectly clean from looking at it, but essentially the guy isn't always perfectly in the center of the screen -- during movement, he's often times a pixel or two off for an instant. Any ideas/ solutions?

  • Excel 2010: if( , , "") not treated the same as blank for pivot table group by date

    - by Confused
    I'm trying to group by date in an Excel 2010 pivot table. The column with dates (i.e., the one want to group by), should be the latest date of 2 other columns if neither is null, or blank. i.e., with a formula like: =IF(AND(A4 <> "", B4 <> ""), MAX(A4,B4), "") Normally, this ""in the IF() formula acts the same as an empty cell. In this case, it is preventing me from grouping by date in the Pivot Table. If I filter the date column by (Blanks), then clear the contents of all those cells, then the pivot table does group by date ok. i.e., "" is not being treated the same as an empty cell.

  • Strengthening code with possibly useless exception handling

    - by rdurand
    Is it a good practice to implement useless exception handling, just in case another part of the code is not coded correctly? Basic example A simple one, so I don't loose everybody :). Let's say I'm writing an app that will display a person's information (name, address, etc.), the data being extracted from a database. Let's say I'm the one coding the UI part, and someone else is writing the DB query code. Now imagine that the specifications of your app say that if the person's information is incomplete (let's say, the name is missing in the database), the person coding the query should handle this by returning "NA" for the missing field. What if the query is poorly coded and doesn't handle this case? What if the guy who wrote the query handles you an incomplete result, and when you try to display the informations, everything crashes, because your code isn't prepared to display empty stuff? This example is very basic. I believe most of you will say "it's not your problem, you're not responsible for this crash". But, it's still your part of the code which is crashing. Another example Let's say now I'm the one writing the query. The specifications don't say the same as above, but that the guy writing the "insert" query should make sure all the fields are complete when adding a person to the database to avoid inserting incomplete information. Should I protect my "select" query to make sure I give the UI guy complete informations? The questions What if the specifications don't explicitly say "this guy is the one in charge of handling this situation"? What if a third person implements another query (similar to the first one, but on another DB) and uses your UI code to display it, but doesn't handle this case in his code? Should I do what's necessary to prevent a possible crash, even if I'm not the one supposed to handle the bad case? I'm not looking for an answer like "(s)he's the one responsible for the crash", as I'm not solving a conflict here, I'd like to know, should I protect my code against situations it's not my responsibility to handle? Here, a simple "if empty do something" would suffice. In general, this question tackles redundant exception handling. I'm asking it because when I work alone on a project, I may code 2-3 times a similar exception handling in successive functions, "just in case" I did something wrong and let a bad case come through.

  • Becoming a "maintenance developer"

    - by anon
    So I've kind of been getting angry about the current position I'm in, and I'd love to get other developers' input on this. I've been at my current place of employment for about 11 months now. When I began, I was working on all new features. I basically worked on an entire new web project for the first 5-6 months I was here. After this, I was moved to more of a service oriented role (which was still great, all new stuff for me), and I was in this role for about the past 5-6 months. Here's where the problem comes in. Basically, a couple of days ago I was made the support/maintenance guy. Now, we have an IT support team, so I'm not talking that kind of support, I'm talking more of a second level support guy (when the guys on the surface can't really get to the root of the issue), coupled with working on maintenance issues that have been lingering in the backlog for a while. To me, a developer with about 3 years of experience, this is kind of disheartening. With the type of work place this is, I wouldn't be surprised if these support issues take up most of my days, and I barely make it to working on maintenance issues. Also, most of these support issues aren't even related to code, they are more or less just knowing the system architecture, working with making sure services are running/getting started properly, handling/fixing bad data, etc. I'm a developer, so this part sucks. Also, even when I do have time to work maintenance, these are basically just bug fixes/improving bad code, so this sucks as well, however at least it's related to coding. Am I wrong for getting angry here? I don't want to really complain about it, but to be honest, I wasn't spoken to about this or anything, I was kind of just sent an e-mail letting me know I'm the guy for this type of thing, and that was that. The entire team took a few minutes to give me their "that sucks" talk, because they know how annoying it is to be on support for the type of work we do, so I know I'm not the only guy that knows it's not that great of an opportunity. I'm just kind of on the fence about how to move forward. Obviously I'm just going to continue working for the time being, no point making a bad impression on anybody, but I'd like to know how you guys would approach this situation, or how you think I should be feeling about it/how you guys would feel. Thanks guys.

  • How would I force Debian to use the physical sector size on a hard disk?

    - by Confused User
    I just purchased a few new 3TB WD drives. These have physical 4k sectors, but there is some sort of layer which is providing 512B logical sectors (see the partition table below). In order to attempt to get some more speed out of my hard drives, I would like to get rid of this logical layer and actually use the physical 4k sectors. However, I can't figure out how to do this (or even if it's possible) from the man pages of fdisk and parted, or from searching Google. Does anybody know how this could be done? As to why this is relevant, this page demonstrates that meerly aligning the sectors properly can already make up to a 25% speed difference for reads, and more than 2500% for writes in some cases! Getting rid of the logical sectors in favor of the physicals ones should improve speeds even more. Thanks! $ parted /dev/sdc GNU Parted 2.3 Using /dev/sdc Welcome to GNU Parted!

  • In a multidisciplinary team, how much should each member's skills overlap?

    - by spade78
    I've been working in embedded software development for this small startup and our team is pretty small: about 3-4 people. We're responsible for all engineering which involves an RF device controlled by an embedded microcontroller that connects to a PC host which runs some sort of data collection and analysis software. I have come to develop these two guidelines when I work with my colleagues: Define a clear separation of responsibilities and make sure each person's contribution to the final product doesn't overlap. Don't assume your colleagues know everything about their responsibilities. I assume there is some sort of technology that I will need to be competent at to properly interface with the work of my colleagues. The first point is pretty easy for us. I do firmware, one guy does the RF, another does the PC software, and the last does the DSP work. Nothing overlaps in terms of two people's work being mixed into the final product. For that to happen, one guy has to hand off work to another guy who will vet it and integrate it himself. The second point is the heart of my question. I've learned the hard way not to trust the knowledge of my colleagues absolutley no matter how many years experience they claim to have. At least not until they've demonstrated it to me a couple of times. So given that whenever I develop a piece of firmware, if it interfaces with some technology that I don't know then I'll try to learn it and develop a piece of test code that helps me understand what they're doing. That way if my piece of the product comes into conflict with another piece then I have some knowledge about possible causes. For example, the PC guy has started implementing his GUI's in .NET WPF (C#) and using LibUSBdotNET for USB access. So I've been learning C# and the .NET USB library that he uses and I build a little console app to help me understand how that USB library works. Now all this takes extra time and energy but I feel it's justified as it gives me a foothold to confront integration problems. Also I like learning this new stuff so I don't mind. On the other hand I can see how this can turn into a time synch for work that won't make it into the final product and may never turn into a problem. So how much experience/skills overlap do you expect in your teammates relative to your own skills? Does this issue go away as the teams get bigger and more diverse?

  • In a multidisciplicary team, how much should each member's skills overlap?

    - by spade78
    I've been working in embedded software development for this small startup and our team is pretty small: about 3-4 people. We're responsible for all engineering which involves an RF device controlled by an embedded microcontroller that connects to a PC host which runs some sort of data collection and analysis software. I have come to develop these two guidelines when I work with my colleagues: Define a clear separation of responsibilities and make sure each person's contribution to the final product doesn't overlap.
