book: Exercises in programming styles, by Chritina Videira Lopes - 10 views

  •  
    "In the 1940s, the French writer Raymond Queneau wrote a jewel of a book called Exercises in Style, featuring 99 renditions of the exact same story, each written in a different style. The story being fairly trivial and always the same, the book highlights form, rather than content; it illustrates how the decisions we make in telling a story affect the perception of that story. Inspired by Queneau, I decided to embark on the project of writing the exact same computational task in as many styles as I have come across over the years. Exercises in Programming Style (#EPSBook) features 33 renditions of a simple computational task -- counting the frequency of words in a given file. All renditions are written in Python. This book is a companion text for code that is publicly available in Github. Software developers with many years of experience may enjoy revisiting familiar programming styles in the broad context of this book and learning about styles that may not be part of their normal repertoire. This book can be used as a textbook for advanced programming courses in Computer Science and Software Engineering programs. Additional teaching materials, such as lecture slides and implementations of each style in other languages, are also available."

The Ideal HPC Programming Language - ACM Queue - 2 views

  •  
    What if programming did not mean having to learn a language someone else devised and then wrestling with the limitations of that language, its compilers, and computers to implement your task? What if it meant, in a sense, the opposite? You could write your program in whatever way was most expressive for you, without regard for language rules imposed by someone else. Then it would be somebody else's job to define the programming language that would make sense of what you wrote, write the compilers to digest the program, and build the computers that would efficiently run the task you specified.

Hadoop! : Apache distributed computing ecosystem - 4 views

  •  
    « The Apache™ Hadoop™ project develops open-source software for reliable, scalable, distributed computing. The Hadoop software library is a framework that allows for the distributed processing of large data sets across clusters of computers using a simple programming model. It is designed to scale up from single servers to thousands of machines, each offering local computation and storage. Rather than rely on hardware to deliver high-avaiability, the library itself is designed to detect and handle failures at the application layer, so delivering a highly-availabile service on top of a cluster of computers, each of which may be prone to failures. »

The dumbing down of technology | Tony Lawrence | 2008 - 0 views

  •  
    I love this article. Lawrence is 60 and can perhaps afford to be sanguine, but I am glad he is warning the rest of us.
  •  
    Some quotable quotes here: "while we laugh at the guy who expected that his computer could be hooked up to his boom box to use the cd, he's actually just a bit ahead of us. Yes, ahead, not behind. In the future, he probably could get his computer to talk the boom box into transferring data from its cd." "When I was a teenager, I had a friend who made extra money testing and changing vacuum tubes in TV's and radios. Try earning money that way today- there is actually a very small market for that kind of thing, and there are still people who sell tubes and the like, but that market is pretty small. In the dumbed down computers of the future, there may still be a few antique machines kicking around here and there, but that isn't going to support very many of us." This is largely true and happening all the time. A programmer can use Python or Smalltalk without needing to know C (or Fortran or assembler.) A child can program in Morphic tiles (Etoys and Scratch)! We don't need to know the difference between a serial cable and a printer cable, or how to install a driver' it is all USB (or Bluetooth!) There are some gurus that program USB, but perhaps only a few hundred of them, and the rest of us just use it.

Joe Duffy's Weblog - OnBeingStateful - 0 views

  • The biggest question left unanswered in my mind is the role state will play in software of the future.
  • The biggest question left unanswered in my mind is the role state will play in software of the future. That seems like an absurd statement, or a naïve one at the very least.  State is everywhere: The values held in memory. Data locally on disk. Data in-flight that is being sent over a network. Data stored in the cloud, including on a database, remote filesystem, etc. Certainly all of these kinds of state will continue to exist far into the future.  Data is king, and is one major factor that will drive the shift to parallel computing.  The question then is how will concurrent programs interact with this state, read and mutate it, and what isolation and synchronization mechanisms are necessary to do so?
  • Many programs have ample gratuitous dependencies, simply because of the habits we’ve grown accustomed to over 30 odd years of imperative programming.  Our education, mental models, books, best-of-breed algorithms, libraries, and languages all push us in this direction.  We like to scribble intermediary state into shared variables because it’s simple to do so and because it maps to our von Neumann model of how the computer works.
  • ...3 more annotations...
  • We need to get rid of these gratuitous dependencies.  Merely papering over them with a transaction—making them “safe”—doesn’t do anything to improve the natural parallelism that a program contains.  It just ensures it doesn’t crash.  Sure, that’s plenty important, but providing programming models and patterns to eliminate the gratuitous dependencies also achieves the goal of not crashing but with the added benefit of actually improving scalability too.  Transactions have worked so well in enabling automatic parallelism in databases because the basic model itself (without transactions) already implies natural isolation among queries.  Transactions break down and scalability suffers for programs that aren’t architected in this way.  We should learn from the experience of the database community in this regard
  • There will always be hidden mutation of shared state inside lower level system components.  These are often called “benevolent side-effects,” thanks to Hoare, and apply to things like lazy initialization and memorization caches.  These will be done by concurrency ninjas who understand locks.  And their effects will be isolated by convention.
  • Even with all of this support, we’d be left with an ecosystem of libraries like the .NET Framework itself which have been built atop a fundamentally mutable and imperative system.  The path forward here is less clear to me, although having the ability to retain a mutable model within pockets of guaranteed isolation certainly makes me think the libraries are salvageable.  Thankfully, the shift will likely be very gradual, and the pieces that pose substantial problems can be rewritten in place incrementally over time.  But we need the fundamental language and type system support first.

Shedding Bikes: Common Programmer Health Problems - 0 views

  • Overall the general cause of all of these problems can be summarized as treating programming as an obsession. You may want to be very good at it, like I did, so you exclude everything else in your life in order to master it. You don't go to the bathroom, you have macho 10 hour coding sessions, you don't eat right, and all manner of mythological beliefs about "real programmers".
  • try to not start at a computer screen for at least 2 hours a whole day
  • Frequently programmers will think that the lighting in a room is what gives them headaches from using a computer, but really it's bad posture, shitty fonts, not drinking enough water, and just using the computer for too long at a stretch
    • omouse
       
      very very true
  • ...3 more annotations...
  • I feel more awake and rested during the day. If I stay up late and sleep in I feel like I have a hangover and I can get headaches.
  • If you constantly feel "stiff" or unable to move well, then you probably need to stretch regularly
  • I'm not sure why this is, but a relaxed mind is crucial to spontaneous creativity and idea generation
  •  
    Programming is a deceptively damaging field to be in, partly because it doesn't seem like you're doing much, and also because of the attitude many programmers have toward their body. You should care about keeping yourself healthy because, when your body is in good shape, that removes "friction" from your mental capacity so that it can focus on important things rather than annoying little problems with your physical wellness.

Programming Proverbs - Computer Science Teacher - Thoughts and Information from Alfred ... - 0 views

  • Interesting comment about IntelliSense encouraging a bottom-up approach. I think that is true if you start with programming and not with design. What I mean by that is that some people create their design in code rather than working out the full design before starting to code. I think that if you create a design using a top down approach it takes longer to get to the building blocks. that is frustrating to many, especially students, but in the long run results in a much better design. With a complete design in place one does know what the little blocks of code will be at least from the standpoint of names and interfaces. Creating those little blocks early on in the programming is fine as long as the design is complete

STXXL : Standard Template Library for Extra Large Data Sets - 4 views

  • The key features of STXXL are:
  • Transparent support of parallel disks. The library provides implementations of basic parallel disk algorithms. STXXL is the only external memory algorithm library supporting parallel disks.
  • The library is able to handle problems of very large size (tested to up to dozens of terabytes).
  • ...4 more annotations...
  • Improved utilization of computer resources. STXXL implementations of external memory algorithms and data structures benefit from overlapping of I/O and computation.
  • Small constant factors in I/O volume. A unique library feature called "pipelining" can save more than half the number of I/Os, by streaming data between algorithmic components, instead of temporarily storing them on disk. A development branch supports asynchronous execution of the algorithmic components, enabling high-level task parallelism.
  • Shorter development times due to well known STL-compatible interfaces for external memory algorithms and data structures.
  • For internal computation, parallel algorithms from the MCSTL or the libstdc++ parallel mode are optionally utilized, making the algorithms inherently benefit from multi-core parallelism.
  •  
    « The core of STXXL is an implementation of the C++ standard template library STL for external memory (out-of-core) computations, i. e., STXXL implements containers and algorithms that can process huge volumes of data that only fit on disks. »
