My primary language is Cobol on large mainframes. Was it the availability of the free GNAT compiler that sparked your interest in the language? I think that if you judge Ada by the number of companies that have a fanatical devotion to the language, you will consider it irrelevant.

There hangs all the time a cloak of secrecy over the Ada projects (if there are any), maybe it is due to the military background of Ada. All the postings concerning this issue are so laconic, that no one can get conception how large is the project, what is the expected result (product) and is it going to be obtained, what kind of mixture of programming languages are used and so on. A few will stand forth and say I (we) did it in Ada, nobody says we tried to do in Ada but failed (I think there are some). In my own case (I do not speak for my company) I would say it is too risky to stay away from the mainstream. First I should have a strong evidence done by me or associates, until I could convince my superiors, but I can't do that evidence without a fairly complete set of Ada tools and support (expensive) or without spending my working hours, for which I don't have acceptance of my superiors...

I've worked on lots of large Ada developments. I've seen or heard of many more. Check out some of the web sites that talk about Ada and I'm sure you will find out about them too. Its not that it isn't used. It is just not used in highly visible applications. (Although I think Netscape and Windows would be better products if it *was* used there! ;-) > A few will stand forth and say I (we) did it in Ada, nobody says we tried to > do in Ada but failed (I think there are some). > I had heard tell of some project the FAA was doing in Ada which failed (as does my aging memory!). However, project failure is often more an issue of bad planning and management than it is the language of implementation. I think the Denver Airport had a baggage handling system written in C or C++ which was a flop, but as much as I'd like to blame it on C, I'd be reasonably sure that a better software process could have made it a success. If the development team understands their tools and the limitations thereof, they can plan for the weaknesses and insure success. I know of no project failures in Ada or any other language that could not have been avoided with a sound process. > In my own case (I do not speak for my company) I would say it is too risky > to stay away from the mainstream.

There are plenty of Ada tools and support available and choosing to use Ada often limits project risks. However, there are problem domains that are better suited to the tools available in another language and then that language becomes the better choice. I'd say that most of the issue revolves around how much understanding the developers have of the language and tools. Diving into a major project while saying "Hey! Let's do it in Ada." without providing any time/budget to get the developers up to speed on how to do it right is a really good recepie for failure. (It would be in any other language as well.) If you don't learn to use the language, you can't derive the benefits that come with it either. My suggestion is that if you think your project would benefit from Ada's features, then find at least one or two developers with considerable experience using it. Let them push the design and guide the other developers in how to use Ada properly. It also doesn't hurt to send the developers to a class and get them some books as well. Its necessary to do this with anything new and is an up-front investment in risk mitigation and back-end productivity. If you want to make a business case for using Ada, look for articles and links at: http://www.AdaPower.com/ I've seen a number of presentations and had much personal experience collecting metrics which demonstrate Ada increases productivity and reduces error rates. Or you could let your competitors adopt the technology and gain a competitive advantage... :-) MDC -- ============================================================= Marin David Condic - Quadrus Corporation - 1.800.555.3393 1015-116 Atlantic Boulevard, Atlantic Beach, FL 32233 http://www.quadruscorp.com/ m c o n d i c @ q u a d r u s c o r p . c o m Visit my web site at: http://www.mcondic.com/ "Capitalism without failure is like religion without sin." -- Allan Meltzer, Economist ============================================================= ^ permalink raw reply [flat|nested] 21+ messages in thread

I think you're referring to the failed attempt a few years ago to develop a new air traffic control system for the U. S. A division of my company was the software subcontractor for the project, which was large- ly in Ada. It's my understanding that when the project was shut down, the manager (from the prime contractor, another company) volunteered that the choice of programming language was not the cause. I'm writing from memory of informal chats with colleagues 3000 miles away, but, from what I heard, it was a classic case of not stabilizing requirements.

For Ada, the problems have come about when the team tries to over-design the system. Ada has many wonderful features, such as tasking, tagged types, etc. However, if over-used (how about 10 levels of inheritance, tasks used essentially as procedures, . . .; not the real problems to protect the innocent) on what was thought at the time to be a fast processor (68010, 80386 DX), these features can be time hogs. Of course the real problem was with the people, not the language. But we Ada lovers tend to say that Ada helps prevent problems. Unfortunately there are people who love abstraction, and abstraction can be a problem if used badly. Please understand that I could easily give many examples of problems with C or C++ programs, but that is not part of this thread. My only point is that there are people who like low-level languages (i.e. C) because it is less abstract (similar to people who like assembly language) and therefore easier to estimate performance.

Done that. Got the T-Shirt. I'm currently working on some code that was apparently written by a bunch of C++ programmers who got sent to an Ada class and then went hog-wild with some of the new features they learned. (This is just a guess, but the code looks kind of C-ish and there I'm seeing the same things you describe: Tasks used as procedures or just overapplied, too many levels of inheritance, too many data types, etc.) While there is evidence that the programmers at least got sent to a class and hence had *some* understanding of what they were doing, there seems to be a lack of experience in designing large systems in Ada at work here. The software is not a "failure" but it could have been improved considerably if the design had been guided by one or more experienced Ada programmers. (Pretty tough to get that experience without building something like this which you just accept as "less than perfect") BTW, I'd expect exactly this sort of quality if you took a bunch of Ada programmers who knew nothing of C++ and dumped them into that environment. Each language has its peculiarities and ways of doing things. We'd probably fight the language going in that direction just as they do coming in our direction. > Of course the real problem was with the people, not the language. But > we Ada lovers tend to say that Ada helps prevent problems. > Unfortunately there are people who love abstraction, and abstraction > can be a problem if used badly. > It ultimately always has to come down to people. Misuse of a tool is not the tool's fault. I'd think that management of a program being done in Ada by a formerly C++ staff would need to consider the tools and see to it that some knowledge and experience is built up on the project before entering into design. Yes, Ada prevents problems, but in my mind the problems it prevents are the superficial design flaws. No language can stop a project from making fundamental design flaws. If a project fails for superficial design flaws (excessive crashes for numeric errors, memory references, etc.) then you might blame the language. If it fails because of fundamental design flaws (excessive complexity leading to size/time problems, overshot schedules trying to integrate incompatible subsystems, etc.) then its not the language but the engineering management that is to blame.

The problem with playing the "mainstream" game, is that mainstream is a quite volatile beast. If your time frame is less than a year or if you can afford to rewrite everything from year to year to follow whatever is "mainstream" at a given time, it's okay. --LG ^ permalink raw reply [flat|nested] 21+ messages in thread

If private enterprise companies which use Ada consider it a competitive advantage (like e-mail and news were 15-20 years ago) then they will be quiet about it. One problem is that much that is written about Ada versus e.g. C++ compares language facilities. This is not particularly relevant since what one wants to know is the impact on the ETS (Effort To Solution). This is where Ada shines. There has been no proper academic study of the impact of programming language on ETS. However there is quite a lot of anecdotal evidence. E.g. the "Ada in Europe" article in Crosstalk journal. The latest I saw in a newsgroup was a company which had decided to go for Ada because their analysis of their errors suggested that Ada would remove 80 % of the problems. In a situation where access to talent may be the limiting factor then a company should not be able to afford not to investigate a tool which may slash ETS by 2/3.

Try looking at www.adapower.com or www.adaic.org. Ada is particularly crucial to large projects where getting the software correct is difficult. When your company builds a 777 aircraft, the big thing to promote is that it keeps flying, and Ada would not be sufficient if there were not jet engines and wings and other pieces. Although folks in this newsgroup might prefer it otherwise, Boeing is not going to stick a big "Ada-inside" logo on every plane. While Ada works just fine for smaller projects (like my program that dials my answering service once an hour), those are not areas where it takes a committee to decide on a language.
