Bad programming skills = biggest hurdle to astronomy research

In summary, the conversation discusses the challenges of dealing with large amounts of data in astronomy and the importance of good programming skills. Scientists and engineers are not always skilled programmers, and it is necessary to have proper training and communication between astronomers and programmers to effectively analyze the data. Hiring dedicated programmers may also be beneficial, but can be costly for universities. Overall, there is a need for collaboration and understanding between different fields in order to tackle the complex task of analyzing astronomical data.

Seems very conceivable to me.

If you look at the amount of data we're currently producing, it's, to use exactly the right word, astronomical. A lot of it hasn't even been sifted through in the correct manner to yield some likely interesting science results. For example, you have a lot of interest right now in detecting extrasolar planets. But the data from this type of analysis, especially on the scale of hundreds of thousands of stars like Kepler, can be immensely useful to discover some stellar physics in its own right. It's just, to sort through it all is such a massive task (no doubt relegated to computers) that programming it all in is undoubtedly a major challenge.

And it's only likely to get worse, as next generation telescopes like the LSST are going to produce even larger amounts of data. In the case of LSST, ~20TB per night of observations. Figuring out how to store, reference, and analyze that is all a programming task of large magnitude.

What are your thoughts on this?

Dead on. From my experience, most scientists and engineers make for incredibly bad programmers. My opinion: The only reason computer science majors are not used to write our scientific /engineering programs is that most computer scientists fare even worse at doing science and engineering than we do at doing programming.

It isn't that hard to program well. We know what a good engineering design or a solid scientific theory looks like. We can learn what a well-constructed program looks like. It does take some training, however. It is a bit arrogant on our part to think that training is not required.

I'd also comment on the computer scientist's inability to do science but I won't push those buttons. Computer scientists aren't inherently better programmers than scientists of any other kind. Here too programming is vaguely taught and encouraged but is not an inherent part of the course.

It might be a good time to reflect on the interaction. Astronomers need to tell the programmers/analysts what they are attempting to tease out of the mountain of data, and they need to explain what they think the tell-tale signs in the data might look like (variations in total flux, variations in peak wavelength, and so on). Programmers need to come up with algorithms that can sift through the data efficiently, and they need to communicate with the astronomers when their output isn't clean or as expected, so that they can get more guidance and modify their search.

It's not rocket-science. Observational astronomy is not hands-on. Your "subjects" are far away, in physical space and in time. You have a suite of instruments to make observations, and you have (often) a mountain of data (often with a high noise:signal ratio) from which to glean some information that may or may not support your preconceptions. It is short-sighted to lay research hurdles on "bad programming", IMO. "Bad communication" is more likely.

If they already have the programs that "work" why not just give them to a programmer and have them make it work well. That way the program does exactly what is intended and all the problems and slow running time can be removed. And who knows it might allow for a much broader or precise search. Much of these differences can be night and day.

Because bad programs cannot be fixed, they must be written as if the original had never existed. The difference between a program that works and one that works well is vastly greater than that between a program that works and one that doesn't work at all.

It sounds like part of the problem was that they couldn't explain to the programmers exactly what they wanted so programmers couldn't do what the already written programs could do.

This is why you give the programs to the programmers and have them see what the program actually does. They can then make a program that gives the same results, but works much better and has more features.

What programmers?

The people who write the astronomical codes discussed in the article are predominantly astronomy grad students. An astronomy department would have to cut two of those grad students to hire one programmer, and for that paltry sum they just might be able to hire a freshout with a BS in IT who graduated well into the bottom half of the class.

That sounds awesome in theory, but works out rather badly when you actually have to figure out somebody's scientific computing code full of all sorts of crazy math, almost no comments, and lots of hacks to keep the code from crashing. I spend a good chunk of time using and rewriting a labmate's code to make it robust enough for my purposes and it's like pulling teeth to get an explanation of the code that makes any sense to me.

I'll chime in that by no means is this limited to astronomy research. I'm in applied CS-the one field where you'd expect to see halfway decent code-and I still see all the same problems 'cause many people assume that they're writing the code as a one off to do some number crunching and therefore don't think about maintainability at all. Actually, I think the biggest hindrance to good code probably is that very few researchers have the luxery of taking a week (or a few weeks) to properly write, test, document, and refactor their code.

The people who write the astronomical codes discussed in the article are predominantly astronomy grad students.
In theory code cleanup would be a great task to farm out to undergrads, but the math involved in the programming makes it totally unfeasible a lot of the time.

Figuring out how to store, reference, and analyze that is all a programming task of large magnitude.
One of the fun things about working with very large datasets is that I'm usually the only person in the room who cares about the space complexity as much (if not more than) the time complexity of any of the algorithms used to do the number crunching.

Because if you can precisely explain exactly what equations need to be programmed, then you've already written the program.

It's easier to teach an astrophysicist how to program well, than it is to teach a programmer astrophysics. While there are astrophysicists that are awful programmers, there are astrophysicists that can program extreme well.
 
  • #12
I trust an astrophysict's 'plodding' algorithms more than I would ever trust a programmer's ability to figure out what it is they are trying to calculate. Yes, the astrophysicist will not write programs as efficiently as an IT major, but, they still work. I see, however, no reason not to run the program by an IT guy to ensure it is doing what they intend it to do.

It is not hard to write effective code, merely to write efficient code. This was an issue 30 years ago when memory was expensive. This is no longer true. You can now write horribly inefficienct code and no one cares - aside from waiting for it to process.

Haha so true. But what about code for supercomputers? (code that might take several days to process?) Or code that, say, requires 8 GM of RAM to process? (seriously, I once had to run code that required 8 GB of RAM for certain parameters).
 
  • #16
Ideally the sciences should be re-structured as a business where there is an IT department that they can work with. The scientists then become the analysts and testers of the code leaving the actual programming to those who know exactly what they are doing.

In my 'field' (minor planets), the most 'efficient' software is generated by amateurs (amateur astronomers) who are expert programmers (do programming for a living) working side by side with the professional astronomers in the field. Yes, the Pros still have their own software but the amateurs software is generally all encompassing, user friendly and produces reliable results much quicker for those who don't have to be experts in the field. The Professionals software came first of course, but the amateurs took it and built it 'better' (better is of course relative to who the user is and the results we get from it)

I have a number of problems with the above. I am having a very hard time parsing your first sentence. For one thing, you are using two words, effective and efficient, that are synonyms / near synonyms of one another. For another, that parenthetical remark is a bit hard to parse. I think you are saying "It is not hard to write effective code. What is hard is writing efficient code." If that is the correct interpretation, I take exception to it.

Moreover, people still do care about performance. Comparisons to what computers could do thirty years ago is a bit misleading. We are now doing things with computers that we simply could not do thirty years ago. A poorly designed, poorly implemented system means I cannot do some kinds of analyses (e.g., a statistically valid Monte Carlo simulation) that I could do were the system designed and implemented better. Instead I am limited to doing a poor man's Monte Carlo because of that poor design.

I'll define "effectiveness" as "doing the job, all of it, correctly" and efficiency as "minimizing use of some particular resource". With this definition, efficiency is but one part of effectiveness.

Performance (efficiency) can paradoxically be both under- and over-emphasized in scientific software. From my experience, scientists and engineers tend to underemphasize performance concerns during system design and overemphasize it late in the game (coding and maintenance). Properly worrying about performance during design can eliminate a lot of problems further on down the road. Where will the performance demons lie? Will the system be used in ways that require us to pay extra attention to resources or outfit the program so as to circumvent resource issues? First worrying about performance during the coding stage leads to implementing the system in a language such as Python or Matlab that is far too slow for the intended use and in programmers who optimize the 99.9% of the code that consumes 0.1% of the CPU time but miss the boat on the 0.1% of the code that consumes 99.9% of the CPU time. First worrying about performance after the system is built leads to even worse nightmares.

A big part of effectiveness is making a system that is understandable, testable, and maintainable. The most efficient code is often difficult to understand, very hard to test, and even harder to maintain. Efficiency goes against almost every other measure of software quality.

This isn't as either-or as it is seeming in this thread.

There are engineers who specialize in writing scientific code. They are fully capable of taking the differential equation (or whatever) and programming the discretized solution. The better ones can do it in any type of hardware. They are fully capable of debugging the physics on their own as long as the physicists supply the test problem and expected answer.

The terabytes/day of data problem is totally different. For this you must use computer scientists. It's just not what engineers or physicists do.
 
  • #19
A few are saying it's either-or. Those are the ones who are saying that programming should be turned over to the IT department. my opinion: Yech.

What I've been saying is that scientists and engineers can learn to program well. It's just not something that most can pick up on their own. Some training is needed. Colleges require students of science and engineering to take a minimum of two or three calculus classes, and often quite a bit more math beyond that. Very few require students of science and engineering to take anything beyond an introductory computer programming class. A lot don't require *any* classes in computer science.

And personally I think that's a good thing, since CS classes are often terrible for teaching application programming. What's not surprising is the number of astronomy Ph.D.'s that are terrible programmers, what is more surprising is the number of CS Ph.D.'s that are terrible programmers.

And it really shouldn't be surprising once you think about it. Just because you are a professor of English literature doesn't mean that you can write good short stories.

It's actually quite hard and getting harder. The key to CPU programming is to keep everything on the L1 cache, which is quite limited and requires a lot of tricks. Then there is GPU and multi-core/multi-threaded programming which adds a different level of complexity.

This is no longer true. You can now write horribly inefficienct code and no one cares - aside from waiting for it to process.

People do care in astrophysics and finance. A simulation can take two weeks, and a factor of 2 speedup makes the difference between a calculation that you can't do and one you can. In finance, what options you can sell often limited by how much compute power that you have.

If you take a PDE and give it to someone that doesn't understand PDE's, the code won't work. Also this type of work is something that physics Ph.D.'s get hired to do.

The terabytes/day of data problem is totally different. For this you must use computer scientists. It's just not what engineers or physicists do.

Some do. Astrophysical CFD simulations can and do general gigabytes of data per second, and if you work on one of those projects, you can get very quickly familiar with the nitty-gritty of data storage. People that work on geological systems routinely deal with multi tetrabyte databases. And then there are the bioinformatics people. Once you've sequenced the human genome, storing that information is non-trivial.

Also if you take the attitude "that's not my job" you aren't going to last very long as a physics student. If you start generating multi-gigabyte/second data, and you don't know the CS to deal with that, then learn it.

The big problem with those courses is that they generally don't give you experience in working on hundred-person project teams with millions of source lines of code. Coding is a form of writing, and you learn to write by writing.

Personally, I think a poetry course is pretty useful for writing good code, since some of the issues that you run into in writing elegant C++ are the same issues that you run into when you write English poetry.
 
  • #26
I'm going to side with two-fish here, especially with regard to working on the bigger projects with dozens and dozens of people.

Working on the bigger projects is where you get a lot of experience in a lot of things. Everything from large scale project design to optimization to effective integration of multiple code bases (think libraries or amalgamation of smaller repositories) is where people need to see the forest from the trees and have a depth that is a synonym for experience.

Also a lot of programming that is taught can be way too theoretical. If you're designing a GUI widget, you have to get your hands dirty and not be stuck in some analysis paralysis where you are overanalyzing the design, structure and so on.

Like twofish said with the writing, to get good at writing you have to write: you can only theorize so much before you have to physically do something to learn.

Waiting for data to process is not labor intensive. Waiting for physicists to gather good data is the labor intensive part. Data gathering algorithms are extremely important in this process. Researchers are not blind to this issue and grad students with excellent programming skills are not rare. This may have been issue 30 years ago, but, not now.

You essentially are talking about the difference between software engineering and computer science. And yes, computer science classes past the introductory CS classes are for the most part terrible about teaching software engineering concepts. The introductory CS classes teach some very basic concepts common to computer science, software engineering, scientific programing, and even IT. Some schools require there students to take at least an introductory CS class, some don't (my undergrad school still does).

What's not surprising is the number of astronomy Ph.D.'s that are terrible programmers, what is more surprising is the number of CS Ph.D.'s that are terrible programmers.
Not all that surprising. I've learned the hard way that resumes from CS and IT grads with no education in engineering or the sciences are best filed circularly.


twofish-quant said:

That problem does not pertain just to computer science classes. Failing to teach how to work collaboratively is in my opinion a shortcoming of a lot of science programs. Engineering curricula on the other hand offer lots of opportunities for undergrads to work in team projects, with a lot of the project lead activities performed by a grad student. Participation in such projects, and having some kind of lead role in particular, is something I look for in evaluating prospects.

The problem is not with course content, but course format. The way that courses are structured just doesn't lend itself to teach "real world" programming. Among the differences

1) real world problems are invariably team graded. Your "grade" depends a lot on how competent the person next to you is. So is it unfair that you get a bad "grade" because the person next to you is incompetent. It may be unfair, but it's real, and one skill is to figure out how to deal with that.

2) real world problems tend to be vague and ill-defined. Classes you get a well defined assignment. Much of the work in real work programming involves figuring out what you need to do. When you do get a set of marching orders, more often than not, those orders are either contradictory or flat out impossible, and dealing with that is part of real world programming.

3) class assignments are short and throw-away. in the real world, you have to work with a pre-existing system, and you never are in a situation in which you have to start from scratch. Also sometimes you have to deal with something that is badly written.

This means that you tend to have emotional reactions to good/bad code. In a class they teach you rules, but there is no emotional connection to through rules. In real world software development, you see bad code, and you react with horror since you know that you'll be spending the next three weeks going through ten thousand lines of code and fixing things.

You can get a lot more experience if you work on an open source project. Also I wasn't kidding when I said that it helps you if you take a course on writing poetry. Poetry classes are usually set up so that you write something and then you go to a room where everyone else in the class tells you how you can improve it. That's usually the dynamics of code reviews.

You're looking at the wrong courses. The sciences really should take a look at engineering education. Cube sats, autonomous vehicles, robots, ... The students work as a part of a team on what is often a multi-year project. That might mean dropping a course on some advanced concept, but that's what grad school is for. Besides, the stereotype of a scientist being someone who works on his own with only a blackboard for company is for the most part fifty years out of date. Most scientists, like most engineers, work in large teams nowadays.

in the real world, you have to work with a pre-existing system, and you never are in a situation in which you have to start from scratch.
Have to start from scratch? Get to start from scratch is more like it. There is nothing like being able to start on something from scratch. No CMMI 3 stuff, very few constraints other than getting the job started. Some other saps have to deal with making that initial design real. Getting that kind of opportunity doesn't happen very often.
Also sometimes you have to deal with something that is badly written.
Or a poor design by the people who don't want to deal with all that CMMI 3 nonsense.

This seems like a good thread to ask this question but what languages would you guys say are the 'best' for writing astrophysics tyoe simulations (i.e. 3+ body problem simulations).

I began with Maple before I had any intentions to program these types of problems and have moved onto Matlab as maple isn't the best for high end computing. I have a feeling C++ would perhaps be a good shout but since I have a course on Matlab this year I'll be mainly working with that. I also find that the more I work with languages like Matlab the more I seem to understand C++ code despite never having worked with it.

I read somewhere that you should look at programming less in terms of learning a language and more in terms of learning the basics and fundementals of programming such as OOP.

This is a website I found a while back, its a great comparison of programming languages and their speed.

http://shootout.alioth.debian.org/fastest-programming-language.php [Broken]

I think you're right in choosing C++ as a language, as you can see, C is minimally faster, but slightly more annoying to code at times so C++ is a happy medium. Speaking of happy medium, I tend to fall into that category when it comes to this topic, my schooling (while not finished) was for Astro-Engineering, but I now hold a job as Linux Sysadmin and have done a rather extensive amount of programming. I think what someone mentioned before its like we have to learn all over again, we've gotten so used to fast computers and not caring about efficiency, but when you are dealing with this large of numbers, it is like going back 30 years with computing power. Unfortunately, I agree that it's a vicious cycle of astronomers not being programmers and vice versa, it makes it hard to program efficiently when you don't know what you're programming, and it takes years of practice to know how to program efficiently.

while(astronomer == programmer)
{
printf(&efficient_program);
}

EDIT: Coming from a background in a variety of languages, I agree with what you said about learning the basics of programming over the language, you'll learn quickly most languages are very similar and you can adapt to them quickly.

Wow, very interesting link! Why is FOTRAN Intel so slow? My professors always told me to use either C/C++ or FORTRAN since they were the fastest.

FORTRAN is nice for MPI/OpenMP integration too (if you want to parallelize things). I'm sure C also has MPI/OpenMP integration, but I'm not sure if it's as fluid.

Eh. The question raised by Simfish immediately arises on seeing stuff like that:
Simfish said:

The answer is (at least) twofold:
  1. They are combining metrics from multiple programs, some of which are not Fortran's forte. Who cares how well Fortran performs in handling strings?
  2. The programs appear to be not so well-written. Some of the so-called benchmarks are so poorly written that they don't even compile. This is a failure of the benchmarking, not of the language.
The tests in which Fortran fares very poorly are in part a reflection of the limitations of Fortran (yes, Fortran isn't so good at handling strings), but also appear to be in part due to giving the programming assignment to someone not well-versed in Fortran.

Note well: I am not a Fortran advocate. Far from it; I gladly abandoned the language a couple of decades ago. One doesn't have to be a Fortran advocate to say that those benchmarks are more than a bit suspect. That said, Fortran does not always look so bad at debian.org. In the n-body problem Fortran is the winner: http://shootout.alioth.debian.org/u32q/performance.php?test=nbody [Broken].

1. What are the main consequences of bad programming skills in astronomy research?

Bad programming skills can significantly hinder progress in astronomy research. It can lead to incorrect data analysis, errors in simulations and models, and difficulty in reproducing results. This can ultimately delay or even prevent the advancement of scientific knowledge in the field of astronomy.

2. How do bad programming skills affect the accuracy of astronomical data?

Astronomical data is often complex and requires sophisticated programming skills to analyze and interpret accurately. Bad programming skills can result in incorrect data analysis, leading to inaccurate conclusions and potentially misleading results. This can have a significant impact on the validity and reliability of research findings.

3. Can bad programming skills hinder collaboration among astronomers?

Yes, bad programming skills can hinder collaboration among astronomers. In order to work together effectively, astronomers need to be able to understand and use each other's code. If one member has poor programming skills, it can be challenging for others to work with their code, leading to delays and potential misunderstandings in the research process.

4. How can bad programming skills be a barrier for aspiring astronomers?

For aspiring astronomers, having good programming skills is essential for success in the field. Without these skills, it can be difficult to analyze data, create models, and collaborate with other researchers. This can limit opportunities for research and career advancement in the field of astronomy.

5. What steps can be taken to improve programming skills in astronomy research?

To improve programming skills in astronomy research, one can attend workshops or courses specifically geared towards scientific programming. Collaborating with experienced programmers and seeking feedback on code can also help improve skills. Additionally, regularly practicing and staying updated on programming techniques and tools can also contribute to improvement in this area.
