• What's the best way of marketing to programmers?

  - by Stuart

  Disclaimer up front - I'm definitely not going to include any links in here - this question isn't part of my marketing! I've had a few projects recently where the end product is something that developers will use. In the past I've been on the receiving end of all sorts of marketing - as a developer I've gotten no end of junk - 1000s of pens, tee-shirts and mouse pads; enough CDs to keep my desk tea-free; some very useful USB keys with some logos I no longer recognise; a small forest's worth of leaflets; a bulging spam folder full of ignored emails, etc... So that's my question - What are good ways to market to developers? And as an aside - are developers the wrong people to target? - since we so often don't have a purchasing budget anyways!

• Subclassing to avoid line length

  - by Super User

  The standard line length of code is 80 characters per line. This is accepted and followed by the most of programmers. I working on a state machine of a character and is necessary for me follow this too. I have four classes who pass this limit. I can subclass each class in two more and then avoid the line length limit. class Stand class Walk class Punch class Crouch The new classes would be StandLeft, StandRight and so on. Stand, Walk, Punch and Crouch would be then abstract classes. The question if there is a limit for the long of the hierarchies tree or this is depends of the case.

• Convincing my coworkers to use Hudson CI

  - by in0de

  Im really aware of some benefits of using Hudson as CI server. But, im facing the problem to convince my coworkers to install and use it. To put some context, we are developing two different products (one is an enterprise search engine based on Apache Solr) and several enterprise search projects. We are facing a lot of versioning issues and i think Hudson will solve this problems. They argued about its productivity and learning curve What Hudson's benefits would you spotlight?

• How do I remove a LOT of indexed pages from Google?

  - by Thierry

  A few weeks ago we have figured out that Google has indexed some information we would rather keep in some confidentiality, in the format of individual PDF files. Our assumption was that this was a problem with our robots.txt we had overlooked. Even though we are not sure whether or not this is the case, we are certain that the robots.txt file is in a valid format and is, according to Google's webmaster tools, blocking the files. However, even after this adjustment that has been made weeks ago, Google still has the PDF files indexed, but does tell us further information cannot be provided due to the robots.txt file being present. As you can hopefully understand, this is unwanted behaviour due to the nature of the documents. I am aware that there is a request page being provided by Google for this purpose, but there are a lot of files. Is there an easier way to get Google to remove all of the files from its search engine? If not, is there anything else you could advise us to do besides manually requesting Google to remove every single page? Thanks in advance.

• I studied electrical engineering. Can I work as a developer? [closed]

  - by FailedDev

  A while ago I finished my Msc in Electrical Engineering and started working as an engineering consultant where I mostly do development work. I am good at picking up languages/technologies tools. I have fiddled with C/C++/C#/perl/ant/bash/html/css etc. Although I have never had a complain for my work, rather the contrary, I just feel that some day, someone will ask me a real hard task which would maybe seem rather trivial for a computer scientist but hard for me. Should I read/do something to become a better developer. Should I pick up a book about design patterns or algorithms for example? Is this normal that I have this kind of "fear"? Sorry if this is the wrong place to post this question. Please notify me so I can close it if this is the case.

• How bad is it to have two methods with the same name but different signatures in two classes?

  - by Super User

  I have a design problem related to a public interface, the names of methods, and the understanding of my API and code. I have two classes like this: class A: ... function collision(self): .... ... class B: .... function _collision(self, another_object, l, r, t, b): .... The first class has one public method named collision, and the second has one private method called _collision. The two methods differs in argument type and number. As an example let's say that _collision checks if the object is colliding with another object with certain conditions l, r, t, b (collide on the left side, right side, etc) and returns true or false. The public collision method, on the other hand, resolves all the collisions of the object with other objects. The two methods have the same name because I think it's better to avoid overloading the design with different names for methods that do almost the same thing, but in distinct contexts and classes. Is this clear enough to the reader or I should change the method's name?

• Supporting and testing multiple versions of a software library in a Maven project

  - by Duncan Jones

  My company has several versions of its software in use by our customers at any one time. My job is to write bespoke Java software for the customers based on the version of software they happen to be running. I've created a Java library that performs many of the tasks I regularly require in a normal project. This is a Maven project that I deploy to our local Artifactory and pull down into other Maven projects when required. I can't decide the best way to support the range of software versions used by our customers. Typically, we have about three versions in use at any one time. They are normally backwards compatible with one another, but that cannot be guaranteed. I have considered the following options for managing this issue: Separate editions for each library version I make a separate release of my library for each version of my company software. Using some Maven cunningness I could automatically produce a tested version linked to each of the then-current company software versions. This is feasible, but not without its technical challenges. The advantage is that this would be fairly automatic and my unit tests have definitely executed against the correct software version. However, I would have to keep updating the versions supported and may end up maintaining a large collection of libraries. One supported version, but others tested I support the oldest software version and make a release against that. I then perform tests with the newer software versions to ensure it still works. I could try and make this testing automatic by having some non-deployed Maven projects that import the software library, the associated test JAR and override the company software version used. If those projects build, then the library is compatible. I could ensure these meta-projects are included in our CI server builds. I welcome comments on which approach is better or a suggestion for a different approach entirely. I'm leaning towards the second option.

• Want to use h264 in my commercial program. What steps should i take?

  - by Jason123

  Want to use h264 in my commercial program. What steps should I take? Here is what I see that needs to be done. I need to buy a license from VideoLan (x264licensing.com) to use the library to encode video into h264 format and I need to buy a license from the MpegLAGroup to use the h264 video encoding in general in my commercial product. Am I right in thinking that? How much do these cost? I don't see selling much since my target is very niche (video game screen capturing).

• How do you protect your software from illegal distribution?

  - by petr k.

  I am curious about how do you protect your software against cracking, hacking etc. Do you employ some kind of serial number check? Hardware keys? Do you use any third-party solutions? How do you go about solving licensing issues? (e.g. managing floating licenses) EDIT: I'm not talking any open source, but strictly commercial software distribution...

• Software mirroring (RAID1) versus "Fake Raid" for new Windows 7 install

  - by kquinn

  I've just ordered two new hard drives for my main desktop and a copy of Windows 7 Professional 64-bit. I'd like to do a clean install of Win7 onto the new drives (leaving my old XP Pro boot partition around for a while in case something goes disastrously wrong, etc.). I want to have them set up in mirrored (RAID-1) mode. My understanding is that Win7 Pro can do software mirroring, but can I set this up directly at install time? If so, how? Note that I'd like the disk to be split into three partitions (OS/Apps&Data/Bulk data), all of which should be mirrored. Would it be better (more reliable or faster) to use my motherboard's hardware RAID support? My motherboard is an older nVidia nForce 680i SLI, which is not the most stable of motherboards, and I'm not sure how trustworthy its RAID1 configuration might be (or if Win7 could even detect and install onto a hardware-mirrored volume). Also, the performance characteristics of RAID1 are rather different than RAID0 or RAID5, and I'm wondering if Win7's software mirroring might actually be faster than hardware RAID1 (for example, I'm more of a Unix admin when I have to wear the sysadmin hat, and I've had great success deploying ZFS; most hardware RAID1 implementations have to read both disks and compare results to look for data errors, but ZFS can read from only one disk in the mirror and just use the built-in checksum, meaning it can have up to 2x the number of reads in-flight, as long as there's no data corruption). Edit: Okay, my question about whether Windows 7 can do software mirroring has been answered, and it can. I'm still unsure whether Windows software RAID or my motherboard's hardware "fake RAID" function is a better choice, though. Remember, I'm only interested in mirroring -- not the more complicated striping or parity operations that generally show the poor performance of crappy motherboard RAID solutions.

• signed software :: installer -- system software and package installer tool (Apple *.pkg)

  - by fyodor78

  Does anybody know a few details about signed software and /Applications/Utilities/Installer.app? I didn't find more at Wikipedia (https://secure.wikimedia.org/wikipedia/en/wiki/Installer_%28Mac_OS_X%29) and the UNIX-Manual (man 8 installer). I have here a valid signature from iLife 11 Installer.app (http://i.imgur.com/Y3raY.jpg). Does this mean I can be 100% sure that nothing is modified? It means I can trust this PKG because signed by Apple? Or did I get something wrong?

• How to estimate the contribution of an individual to a software project?

  - by Amit Kumar

  I work on a software project and would like to estimate the percentage out of the total contribution that I have put in the development of the software. Is there some tool doing this? Such a tool can be useful for appraisals or negotiations, for example. After all, we work for money (yes, not only money, put the point remains). I think there is enough hand-waving for the most important things. The estimation is very subjective (at least to me now) but I do not know of any tool that provides even a subjective estimate. I know of Sloccount that spells out the total effort using the lines of code but not on per-developer basis. My idea of an ideal tool for this purpose would: measure the complexity of the code (more complex is more effort, but more effort is not necessarily more contribution) measure the decomposibility/flexibility of the software (more decomposable is better) how much library code is used -- using library code speeds up the development process, increases the associated risk and requires the developer to know from before or learn about the library. be intelligent enough to differentiate between "who wrote the code", "who copied the code" and "who indented the code". It is difficult to differentiate between the complexity in the implementation and the intrinsic complexity of the problem. Perhaps a comparison can be made with an equivalent open source counterpart if there is, or for each submodule separately. If there is no such tool, is there no merit in having such a tool? Or do you believe in "I do work, I do not measure"? It takes time after all. Perhaps the project manager should do this estimation continuously, say, weekly. Are there any standards? Yes, standardization is difficult because every project has a different goal, but difficult does not mean it is not useful.

• Software RAID 10 on Linux

  - by vpetersson

  For a long time, I've been thinking about switching to RAID 10 on a few servers. Now that Ubuntu 10.04 LTS is live, it's time for an upgrade. The servers I'm using are HP Proliant ML115 (very good value). It has four internal 3.5" slots. I'm currently using one drive for the system and a RAID5 array (software) for the remaining three disks. The problem is that this creates a single-point-of-failure on the boot drive. Hence I'd like to switch to a RAID10 array, as it would give me both better I/O performance and more reliability. The problem is only that good controller cards that supports RAID10 (such as 3Ware) cost almost as much as the server itself. Moreover software-RAID10 does not seem to work very well with Grub. What is your advice? Should I just keep running RAID5? Have anyone been able to successfully install a software RAID10 without boot issues?

• AS2 Server Software Costs

  - by CandyCo

  We're currently using Cleo LexiCom as our server software for receiving EDI transmissions via the AS2 protocol. We have 7 trading partners per year, and this runs us about $800/year for support from Cleo. We need to expand from 7 trading partners to 10 or so, and Cleo charges roughly $600 per new host, plus an expanded yearly support fee. My question(s) are: Does anyone know of a cheaper developer of AS2 server software, and perhaps one that doesn't charge per new host? Does anyone have any clue why we are being charged an upfront fee for new hosts, and if this is a standard practice for AS2 software providers? It seems really odd that we are required to pay upfront costs for this. I could completely understand an increase in the yearly support, however.

• Tool needed for remote software deployment to Windows PC's over internet

  - by user56527

  Hi Can anyone recommend a commercial software package that enables automated rollouts of a bespoke software package across the internet? We are looking at approximately 1000 remote PC's that our organisation owns, geographically scattered and with varying bandwidths available from a central site. The PC's are not manned, they are used as server machines. The tool needs to have some scripting facilities too. The tool needs to be able to push software to the remote site in an automated way. We also need it to be able to reboot the remote machine too. Any ideas anyone? thanks.

• Good translation (manually) software

  - by S.Hoekstra

  I'm looking for a good translation software. i do not mean something that does all the translation automatically for me. But rather something that aids me in translating large pieces of text, since it has to be a perfect translation i can't leave it to computers alone. Something like http://translate.google.com/toolkit but with more options/functions would be great. Preferably freeware ofcourse (But paid is not a problem). At the moment i use the Google toolkit since it's adequate for now, but i really need something more advanced. But looking for such software on google etc. is really hard because of the confusion with translation services and things like babelfish. Do you know any software like this? and maybe want to share your thoughts/experiences.

• software to emulate a blackboard over internet

  - by Abhijith Madhav

  I need to tutor my brother on a particular topic. We live in different geographical areas. We use g-talk to do the same. We do not have web-cam's to enable video chat. The tutoring will involve a lot of off-the-cuff illustrations. I am hence searching for a suitable software which will emulate a blackboard over an internet connection. I need the software to enable sharing of a common canvas on which I can draw, write and point to. Say a Microsoft paint canvas on internet. Could you point out a suitable software? Google is not of being help at the moment as I suspect that I am not specifying my search criteria properly.

• software creating top view maps

  - by Pennf0lio

  Hi, Please suggest a good software that lets you create top view maps like . I know photoshop and illustrator. But It would make my life easier if there are software that already does this. If I would do it in photoshop, I would have to worry more about textures and object. I would so worry about the size, It should be scalable and would look good in print and screen. I more likely to recreate those object in photoshop. Please suggest a good software or approach to do this. Thanks!

• dual/multi-boot computers and software licensing

  - by Matt

  Suppose you have a computer with two or more operating systems, and a certain piece of software whose license terms allows it to be installed on one computer, and it does a daily check with a remote server to verify that your serial is only used on the original install computer. You install this software on each of your OSes, but since its a different OS the remote server would have to determine that it is not on the same computer, and so would disable your license. So my question, when a license refers to a single computer, does a situation like this usually count as a single computer, or do the multiple OSes sort of make it multiple computers? How do you think a software vendor (specifically thinking AV companies that do this sort of serial check) would handle this situation?

• CD/DVD cataloging software?

  - by NoCanDo

  I'm looking for freeware, or preferably open source CD/DVD cataloging applications. Right now I'm testing http://www.gentibus.com/us/Download.htm, anyone got any other suggestions? I'd like the software to be actively maintained and not released and left behind. I'm looking for software which allows me to catalog, sort, search my DVDs/CDs into databases. Like I've 1 group of 10 dvds only with Fonts etc. I want to read the content into a Database called "Fonts'". Another group of 5 DVD's with Stockimages, and I want to read all 5 DVDs into the Database "Stock Images". Then I want this software to be able to open Database "Stock Images", I want to be able to browse DVD 1 - 5 and to see DVD 1 - 5's contents without having the DVD's in the optical drive.

• How can I prevent users from installing software?

  - by Cypher

  Our organization is a bit different than most. During certain times of the year, we grow to thousands of employees, and during off-times, less than a hundred. Over the course of a few years, many thousands of people have come and gone in our offices, and left their legacy behind in the form of all sorts of unwanted, unapproved, (and sometimes unlicensed) software installs on our desktops. We are currently installing redundant domain controllers and upgrading current servers, all running Windows Server 2008 Enterprise, and will eventually be able to run a pure 2008 DC network. With that in mind, what are our options in being able to lock down users, such that they cannot install unauthorized software on systems without the assistance (or authorization) of the IT group? We need to support approximately 400 desktops, so automation is key. I've taken note of the Software Restrictions we can implement via Group Policy, but that implies that we already know what users will be installing and attempting to run... not quite so elegant. Any ideas?

• What is the actual difference between Computer Programmers and Software Engineers? Is this description accurate?

  - by Ari

  According to the Bureau of Labor Statistics, this is the difference: Computer programmers write programs. After computer software engineers and systems analysts design software programs, the programmer converts that design into a logical series of instructions that the computer can follow They predict employment to increase for software engineers by 34% but to decline for programmers. Is there actually any such real distinction between the 2 jobs? How can one get a job designing programs (to be implemented by others)?
